Quality Assurance
Figure 1 and 2 show the most important stages of the QA
system. Quality assurance (QA) departments, independent
of production and development, are responsible for the
selected measures, acceptance procedures and information
feedback loops. Operating QA departments have state-of-
the-art test and measuring equipment at their disposal, work
according to approved methods of statistical quality control,
and are provided with facilities for accelerated life and
environmental tests used for both qualification and routine
monitoring tests.
1
Quality Assurance
The high quality and reliability of integrated circuits from
Siemens are the result of carefully managed design and
production which is systematically checked and controlled at
each stage.
The procedures are subject to a quality assurance system;
full details are given in the brochure “Quality Assurance
lntegrated Circuits”.
The latest methods and equipment for preparation and
analysis are employed to achieve continuity of quality and
reliability.

Conformance
The general course of IC failure rate versus time is shown by
a so-called “bathtub” curve.The failure rate has its peak
during the first few operating hours (early failure period). After
the early failure period has ended, the “constant” failure rate
period starts during which the failures may occur at an
approximately uniform rate. This period ends with a repeated
rise of the curve during the wear-out failure period. For ICs,
however, the latter period usually lies far beyond the service
life specified for the individual equipment. Reliability tests for
ICs are usually destructive examinations. They are,
therefore, carried out with samples. Most failure mechanisms
can be accelerated by means of higher temperatures. Due to
the temperature dependence of the failure mechanisms, it is
possible to simulate future operational behavior within a short
time by applying high temperatures; this is called life test. The
acceleration factor F for the life test can be obtained from
Arrhenius’s equation
Each integrated circuit is subjected to a final test at the end of
the production process. These tests are carried out by
computer-controlled, automatic test systems as hundreds of
thousands of operating conditions as well as a large number
of static and dynamic parameters have to be considered.
Moreover, the test systems are extremely reliable and
reproducible. The quality assurance department carries out a
final check in the form of a lot-by-lot sampling inspection to
additionally ensure the minimum percent defectives to
ensure statistically that the PDA of released lots is less than
the AQL agreed. Sampling inspection is performed in
accordance with the inspection plans of DIN 40080, as well
as of the identical MIL-STD-105 or IEC 410.

3.1 Measures taken during development
The reliability of ICs is already considerably influenced at the
development stage. Siemens has, therefore, fixed certain
design standards for the development of circuits and layout,
e.g. specifying minimum width and spacing of conductive
layers on a chip, dimensions and electrical parameters of
protective circuits for electrostatic charge, etc. An
examination with the aid of carefully arranged programs
operated on large-scale computers guarantees the
immediate identification and elimination of unintentional
violations of these design standards.
where T2 is the temperature at which the life test is
performed, T1 is the assumed operating temperature and
k is Boltzmann’s constant.
Important for factor F is the activation energy EA. It lies
between 0.3 and 1.3 eV and differs considerably for
individual failure mechanisms.
For all Siemens ICs the reliability data from life tests is
converted to an operating temperature of TA = 55 °C,
assuming an average activation energy of 0.5 eV. The
acceleration factor for life tests at 125 °C is thus 22,
compared with operational behavior. This method considers
also failure mechanisms with low activation energy, i.e. which
are only slightly accelerated by the temperature effect.
3.2 In-process control during production
The manufacturing of integrated circuits comprises several
hundred production steps. As each step is to be executed
with utmost accuracy, the in-process control is of outstanding
importance. Some processes require more than a hundred
different test measurements. The tests have been arranged
such that the individual process steps can be reproduced
continuously.
Various reliability tests are periodically performed with IC
types that are representative of a certain production line this
is described in the brochure “Quality Assurance Integrated
Circuits”. Such tests are e.g. humidity test at 85 °C and 85 %
relative humidity, pressure cooker test, as well as life tests up
to 1000 hours and more. Test results are available in the form
of summary reports.
The decreasing failure rates reflect the never ending effort in
this direction; in the course of the years they have been
reduced considerably despite an immense increase in IC
complexity.

structures for the main oscillator circuit. Alternatively the
oscillator signal can be supplied from an external source. The
oscillator signal is buffered for off-chip use.
• Transmitter with I/Q modulator
• Direct I/Q modulation
• Generation of orthogonal carriers with possibility of phase
adjust with external resistors
• 30-dB carrier rejection, 40-dB SSB rejection
• 48-dB rejection of third order products with 500-mVpp
I/Q-drive level
• High output power with appropriate power matching
network at 500-mVpp I/Q-drive level
PMB 2240: – 3 dBm, PMB 2245: – 6 dBm
PMB 2247: – 8 dBm
• Integrated active part of RF oscillator
• Possibility to use external RF-oscillator signal
• The RF-oscillator signal is buffered for off-chip use,
especially for receiver PMB 2405/07
• Prescaler for the RF-oscillator signal
• Possibility to use the IF oscillator integrated on the
PMB 2405/07
There is a prescaler by 64/65 for the RF-oscillator signal on
chip, which can be used to implement the PMB 2307 PLL
circuit.
The on-chip FIX-PLL consists of the system clock divider, the
IF-oscillator signal divider, the phase detector and the charge
pump. The IF-oscillator signal divider is driven by the
oscillator on the PMB 2405/07 or by an external discrete
VCO. The IF-oscillator signal divider ratio of PMB 2240 and
PMB 2245 is fixed. It can be selected either divided by 1 or by
3 using PMB 2247 and PMB 2407 to drive the FIX-PLL with
two IF frequencies (450 MHz or 150 MHz) to avoid spurious
problems for PCS application.
The two oscillator signals (IF and RF) are combined in the
transmit mixer, and the image sideband and other mixing
products are to be suppressed by an external interstage filter.
The filtered signal reenters the chip at the modulator inputs.
The modulator generates two orthogonal carriers which are
mixed with the I- and Q modulation signals by two multipliers.
The phase between the two carriers can be fine-adjusted to
90° (orthogonality) by two external resistors for maximum
SSB suppression. The outputs of the multipliers are added
and amplified by a linear output stage.
• Possibility to use external IF-oscillator signal
• Fixed IF frequency PLL (FIX-PLL) for IF-VCO (PMB 2240,
2245), switchable IF PLL working at 450-MHz or 150-MHz
IF frequency (PMB 2247)
• Supply voltage range 2.7 to 5.5 V
• P-TQFP-48 package
• Temperature range – 30 °C to 85 °C

capability
• Wide input frequency range up to 2.5 GHz
• Wide IF range from 40 MHz to 300 MHz
• Supply voltage range 2.7 to 4.5 V
• P-TQFP-48 package
The input signal is amplified by the internal LNA and filtered
by an external filter. The filtered signal and the first local
oscillator signal LO1 are mixed down to an intermediate
frequency (IF). The amplification of the IF signal is performed
by a digitally programmable gain-controlled amplifier.
The second local oscillator signal LO2 is generated either by
an on-chip oscillator or by an external VCO. The internal LO2
signal is fed to a divider (PMB 2405-by 1; 2407-by 1 or 3) and
then to a buffered output and also to a divider, which
generates orthogonal signals at half the VCO frequency. The
filtered IF signal re-enters the chip at the IF input, where it is
amplified and converted to the final output frequency with
each of the orthogonal signals. The resulting in-phase and in-
quadrature signals pass through differential output drivers.
• Temperature range – 30 °C to 85 °C
Two differential operational amplifiers can be used as active
baseband filters. At both outputs the differential offset is
sensed via the sample and hold circuitry. A feedback loop
corrects the remaining offset error below the tolerable input
value of the GAIM PMB 2905 or any other baseband A/D
converter.

Introduction
The era of the mobile communications has lead to an
explosion in the variety of RF applications. Active for many
years in this field with high performance IC solutions,
Siemens RF ICs have found use in almost all wireless
systems and are generally recognized for their high
performance, functionality and cost-effectiveness.
Building upon the success of the PMB 2200 modulator
family, the PMB 2401 receiver and Siemens PLLs
(TBB 200/TBB 206/PMB 2306), the new B6HF 25 GHz
bipolar technology will allow for a further increase in
performance, 3-V lower current consumption as well as for
higher frequencies. Starting with the new prescalers
PMB 2313/2314, all the standard RF-building blocks will be
gradually moved to B6HF.

Features
The circuit consists of high speed dual modulus dividers, shift
registers, programmable counters (2 A-, 2 N- and
2 R-counters), phase detectors with charge pump and a
control logic block.
• Integrated prescaler
• Low operating current
• Different power-down modes

handle frequencies of up to 1.25 GHz (2.5 GHz), there is no
need to add a dedicated external prescaler. The second dual
modulus divider handles frequencies up to 500 MHz. The
switching signals for the dividing ratios are generated by the
corresponding A-counters.

PMB 2306
PMB 2307
General Description
Type
Package
The PMB 2306, PMB 2307 PLL are high speed CMOS ICs
are especially designed for use in battery-powered radio
equipment and mobile telephones. The intended application
will be in GSM, PCN, DECT and other digital mobile systems.
The wide range of dividing ratios also allows application in
analog systems.

Adjustment to the “actual” value then takes place with the
usual transient response as for small transfers in channel.
The synchronous transmission ensures that no additional
phase errors arise due to the change of reference
frequencies.
The circuit consists of a reference-, A- and N-counter, a
dual-modulus-control logic, a phase detector with charge
pump and a serial control logic. The setting of the operating
mode and the selection of the counter ratios is done serially
at the ports CLK, DA and EN.
The PMB 2306/2307 has two standby modes (standby1, 2)
to reduce the current consumption.
The operating modes allow the selection of single or dual
operation, asynchronous or synchronous data acquisition,
4 different antibacklash-impulse times, 8 different PD-output
current modes, polarity setting of the PD-output signal,
adjustment of the trigger-edge of the MOD-output signal,
2 standby modes and the control of the multifunction outputs
MFO1 and MFO2.
• Standby1 switches off the whole circuit, the current
consumption is reduced to below 1 µA.
• Standby2 switches off the counters, the charge pump and
the outputs, only the preamplifiers stay active.
The standby modes do not affect the port output signal. For
the influence on the other output signals see standby table.
The reference frequency is applied at the Rl input and scaled
down by the R-counter. Its maximum value is 50 MHz. The
VCO frequency is applied at the Fl input and scaled down by
the N- or N/A-counter according to single or dual-mode
operation. The maximum value at Fl is 220 MHz at single-,
and 65 MHz at dual-mode operation.
Features
• Low operating current consumption
• Low operating voltage
PMB 2306: 3 V to 5.5 V
PMB 2307: 2.7 V to 5.5 V
The phase detector is frequency and phase sensitive. It
produces a phase detector signal with adjustable anti-
backlash impulses in order to prevent a dead zone at very
small phase deviations. Phase differences smaller than
100 ps can therefore be resolved.
• High input sensitivity, high input frequencies (220 MHz)
• Extremely fast phase detector without dead zone
• Linearization of the phase detector output by current
sources
• Synchronous programming of the counters
(N-, N/A-, R-counters) and system parameters
• Fast modulus switchover for 65-MHz operation
• Switchable modulus trigger edge
• Large dividing ratios for small channel spacing
– A-scaler 0 to 127
– N-scaler 3 to 16380
– R-scaler 3 to 65535
• Serial control (3-wire bus: data, clock, enable) for fast
programming (fmax 5 MHz)
• Switchable polarity and rate of trimming rise of the phase
detector
• 2 multifunction outputs
• Digital phase detector output signals (e.g. for external
charge pump)
• frn, fyn outputs of the R- and N-scalers
• Port 1 output (e.g. for standby of the prescaler)
• External current setting for PD output
• Lock detect output with gated antibacklash pulse (quasi
digital lock detect)
Programming of the IC is done by a serial data control. The
contents of the messages are assigned to the functional units
according to the destination address. Single or dual-mode
operation as well as asynchronous or synchronous data
acquisition is set by status 2 and should therefore precede
the programming of the counters.
The PMB 2306/PMB 2307 offer the possibility of
synchronous data acquisition to avoid error signals at the
phase detector due to non-corresponding dividing factors in
the counters produced by asynchronous loading.
Synchronous programming guarantees control during
changes of frequency or channel. That means that the state
of the phase detector or the phase difference is kept
maintained, and in case of “lock in”, the control process starts
with the phase difference “zero”.
Synchronous transmission is particularly advantageous
when large transfers in channel are to be made in a specific
short transient recovery time. For this purpose a larger
reference frequency is switched to in order to achieve rapid-
“rough”-transient response, increasing the bandwidth of the
loop at the time. When reaching the “quasi lock-in” state, the
reference frequency is switched back to its original values.

Overview on ICs for Digital Terminals
ISDN Voice Terminals
The adaptation of existing data terminals (DTE) to an ISDN
through a variety of interfaces (X.21, V24, RS232C, …) is a
subject being covered by a number of emerging standards.
With the digitization of the local loops, new ICs are needed to
adapt the voice and data sources.
The ITAC ISDN adapter circuit PSB 2110 brings a flexible
solution to each configuration.
Because of the analog/digital conversion is implemented in
the telephone, Digital Signal Processing techniques (DSP)
are suitably powerful tools for accomplishing this task. The
ARCOFI® PSB 2160, ARCOFI®-BA PSB 2161 and
ARCOFI®-SP PSB 2165 or PSB 2163 make the best use of
this technology to deliver programmable, telephone specific
codec/filter.
A typical subscriber terminal configuration is shown in the
figure 1.
The modular concept allows the support of several interfaces
like U (ISAC®-P), U (ISAC®-P TE, SmartLink-P), S
P0
PN

(ISAC®-S, ISAC®-S TE) and U (IEC-Q, IEC-T). All interface

Overview on ICs for Digital Terminals
ISDN Data Access
The shown enhanced passive PC-card version (figure 3)
includes the interface controllers and a DSP-based solution.
There is a dedicated ROM-coded DSP-version for supporting
modem (V.32), fax (V.29), data adaption (V.110, USART
framing) and HDLC controlling in development. Please
contact the Siemens sales office for details.
Shorter dial-up times, higher data rates and simultaneous
voice/data transmission comparing to analog transfer via
modem make ISDN very interesting for data access.
Especially ISDN data transfer via PC card is becoming more
and more popular.
Like the ISDN Voice Terminals (figure 1) both PC-card
version are expendible for voice and active PC-card
solutions.

General Exchange Architecture
Analog Line Cards
The conventional implementation is also characterized by
the fixed adjustment of line interface conditions although
telephone line conditions vary considerably with national
standards and even with subscriber line installations. Under
adverse conditions telecommunication equipment must
match the subscriber line and termination impedances while
suppressing return echoes in the two to-four-wire hybrid
network. Compensating for line attenuation is just as critical
for balancing the voice signals in the transmission and
reception paths. To improve voice quality, subscriber line
boards have to be matched to different line conditions by
means of interchangeable discrete components. This
approach is very costly regarding line board design and
manufacturing. Furthermore, the reliability of a board filled
with parts, wires and connections will decrease rapidly.
In a digital exchange system the subscriber line boards
provide the link between the subscriber and the switching
network. The basic functions of analog line boards are
known under acronym BORSHT (Battery, Overvoltage,
Ringing, Supervision, Hybrid, Testing). Additional important
tasks are voice frequency band limitation, analog to digital
conversion into time discrete digital equivalents, time-slot
assignment on the PCM highways and handling of
signaling and control information.
The conventional implementation uses two PCM ports
and one µP interface per subscriber line leading to a large
amount of wiring and, thus, problems are as crosstalk and
large board size.
The best solution to eliminate these line card trouble spots is
the design of one standard line card, which can be
customized for various line conditions and postal
specifications through software control. The right choice of
dedicate device allows the optimal line card design for each
application in public switches, PBX systems as well as in all
kinds of multiplexers and concentrators.

Optimized Line Board Architecture
The Siemens Semiconductor concept is characterized by a
centralized PCM interface controller device providing the
variable Time-Slot Assignment (TSA), the communication
with up to 64 subscriber line devices such as a signal
processing codec/filter (SICOFI) or ISDN devices via the SLD
(Subscriber Line Data) or IOM-2 (ISDN Oriented Modular)
interface, and the interface with a microprocessor.
The use of the signal processing codec/filter (SICOFI) avoids
the analog network which has to be matched to different
requirements by interchanging its discrete components.
Based on Digital Signal Processing (DSP) methods the
SICOFI allows the complete control of the line conditions by
software.
The all-over flexibility and programmability of the unique
device concept gives the user the capability for designing a
standard line card which can be optimized for each
application and can be matched to various line conditions.
As a characteristic architectural feature, for test, monitoring,
and control purposes, the device permits efficient switching
of data streams between all these interfaces and, therefore,
ensures transparency between the PCM channels and
control or signaling data. This opens up attractive
possibilities such as common-channel signaling and
microprocessor access to PCM data.
The SLD/IOM-2 architecture leads to a highly modular line
board configuration with low wiring, reduced board area, and,
dependent on the SLIC being used, very few external
discrete components.

Siemens ICs for Analog Subscriber Lines, Configurations and Interfaces

SLD/IOM®-2 Interface
The SLD-bus is used by the PIC (PCM Interface Controller)
to interface with the subscriber line devices. A Serial
Interface Port (SlP) is used for the transfer of all digital voice
and data, feature control and signaling information
between the individual subscriber line devices, the PCM
highways and the control backplane. The SLD approach
provides a common interface for analog or digital per-line
components. Through the PIC, which is the key device in
the SLD-architecture, the PCM data is transparently
switched onto the PCM highways. The PBC (Peripheral
Board Controller) will make analog and digital subscriber line
boards plug-compatible in a line equipment rack.
Channel A and B are 64-kbit/s channels reserved for voice or
data to be routed to and from the PCM highways. In an
application where one SICOFI is connected to a SIP, voice is
received on channel A and transmitted on channel A and B.
For a three-party conference, channel B is the third-party
voice channel. If two SlCOFls are connected to one SIP,
channel A is assigned to one and channel B to the other
SICOFI. Conferencing is not possible in this configuration.
With digital subscriber line devices the two bytes can be used
to carry 64-kbit/s data channels. The third and sixth byte
locations are used to transmit and receive control information
for programming the slave devices. The last byte in each
direction is reserved for signaling data.
There are three wires connecting each subscriber line device
and the PIC: two common clock signals shared among all
devices, and a unique bidirectional data link for each of the
eight SIP lines. The Direction signal (DIR) is an 8-kHz clock
output from the PIC (master) that serves as a frame sync to
the subscriber line devices (slave) as well as a transfer
indicator. The data are transferred at a 512-kHz rate, clocked
by the Subscriber Clock (SCLK). When DIR is high (first half
of the SLD 125 µs frame), four bytes of digital data are
transmitted on the SLD-bus from the PIC to the slave (receive
direction). During the second half of the frame when DIR is
low, four bytes of data are transferred from the slave back to
the PIC (transmit direction).

Frame Structure of the SLD Interface
The lOM®-Revision-2 (IOM®-2) standard defines an industry
standard serial bus for interconnecting telecommunication
ICs. The standard covers line card, NT1, and terminal
architectures for ISDN and analog loop applications.
By providing data, control, and status information over a
serial channel, the IOM-2 bus eliminates the need to have a
microprocessor interface on the transceiver or codec. This
reduces pin count and simplifies line-card layout, thus
reducing cost.
The line-card mode of IOM-2 provides a connection path
between line transceivers (ISDN) and codecs (analog), and
the line-card controller; the line card controller provides the
connection to the switch backbone. The IOM-2 bus time
multiplexes data, control, and status information for up to
eight ISDN transceivers or up to 16 codec/filters over a single
full-duplex interface.
Information is multiplexed into frames, which are transmitted
at an 8-kHz rate. The frames are subdivided into from one to
eight subframes, with one subframe being dedicated to each
transceiver or pair of codecs. The subframes provide
channels for data, programming, and status information for a
single transceiver or a codec pair.
Siemens Aktiengesellschaft
87
SLD/IOM®-2 Interface
The channel structure of the IOM-2 interface is as follows:
• The fourth octet (control channel) contains
– two bits for the 16-kbit/s D-channel
– a four-bit command/indication channel, in ISDN
applications or
a six bit command/indication channel for analog
subscriber applications
– two bits MR and MX for supporting the monitor
channel protocol.
• The first two octets constitute the two 64-bit/s
B-channels.
• The third octet is the monitor channel. It is used for the
exchange of data between devices using the IOM-2
monitor channel protocol.

Extended Line Card Controller (ELIC®)
PEB 20550
General Description
Type
Package
P-MQFP-80-1 (SMD)
The Extended Line Card Controller (ELIC) PEB 20550-H is a
device to allow the control, supervision and processing of
voice, data and signaling information. It also provides access
for the microcontroller to write/read data to/from the IOM and
PCM interfaces and gives control over layer-1 devices.
Revolutionary is the multiplexing concept allowing to use only
one implemented HDLC controller to process the signaling
information for up to 32 digital subscribers.
PEB 20550-H
The SACCO B is a second integrated HDLC controller
behaving like an external device. It is mainly intended for
signaling information between the line card and the group
processor on the main board. This can be done either via a
dedicated signaling highway or via the PCM highway. The
SACCO B can also be used for music on hold, conferencing
access and other features. The HDLC information handling
between SACCO A and SACCO B always has to go via a
microprocessor.
The switching part of the ELIC controls space and times
switching functions between subscriber line devices and time
division multiplex highways. Furthermore it controls the flow
of information between the subscriber interface ports and a
processor.
Features
For processing signaling information two different HDLC
controllers are implemented. The SACCO A is a Serial
Access Communication Controller (HDLC) which allows
extracting D-Channel information transported on the IOM
interface. The data is then passed to the microcontroller. ln
the downstream direction, the SACCO A passes data,
packed in the HDLC protocol, from the microcontroller to the
IOM interface.
• Configurable interface (CFI) programmable for IOM-2,
IOM-1, SLD or PCM
• Switching between configurable interface (e.g. lOM-2) and
PCM ports
• Switching of 64 B-channels (32 digital or 64 analog
subscribers) without blocking (128 × 128 matrix)
• Two HDLC controllers with 64-byte FlFOs implemented
• Arbiter logic to use one of the HDLC-controllers time
multiplexed for a maximum of 32 digital subscribers
• Full-duplex signaling protocols (LAPD or proprietary)
• HDLC broadcast messages
With 4 IOM interfaces, and 8 digital subscribers possible per
interface, former designs needed 32 HDLC controllers (one
for the D-channel of every subscriber). The SACCO A of the
ELIC can serve all 32 channels in a time-multiplexing
manner. This process is controlled by the BUS ARBITER.
This part of the ELIC monitors all D-channels of the IOM
interface and locks the SACCO A onto one D-channel as
soon as the start of a HDLC frame is detected. After the end-
flag of the HDLC frame has been received, the SACCO A is
released again and can lock onto the next D-channel as soon
as a new request is detected. During the assignment of the
HDLC controller to a certain channel the other subscribers
are not allowed to send information on their D-channels. To
assure this a blocking mechanism is implemented which
indicates to corresponding terminals that they may not use
the D-channel. This mechanism works as well for the
• DMA access to HDLC data
• Boundary scan
Application Areas
• PBX:
– analog line cards
– digital line cards
• CO:
– analog line cards (with disabled arbiter)
– digital line cards (with disabled arbiter)

• 4 configurable interfaces (individually programmable for
IOM, SLD, PCM)
• 4 PCM interfaces (maximum combined data rate
of 8 Mbit/s)
• µP interface (Siemens/lntel and Motorola interface,
multiplexed and demultiplexed address/data bus)
• Boundary scan (for on-board tests)
• DMA interface
wire ISDN capable interface for PBXs. Any ISDN Telephone
can be connected to a PBX because the standard arbitration
mechanism is used for blocking the phones.
This concept saves the space and the costs of up to
32 HDLC controllers. Due to the bursty characteristic of the
signaling data, one HDLC controller is sufficient to process
this data flow. For central office applications the ELIC is not
recommended when the arbiter is used, as PTTs require
transparent D-channels. In this case the SACCO A can be
used as an independent HDLC controller.
If the design needs higher D-channel data rates additional
HDLC controllers (IDEC, PEB 2075) can be connected. This
can either be done on the IOM interface and is than fixed for
a certain subscriber or via the PCM interface which makes
this extra HDLC controller flexibly assignable.

Signal Processing Codec Filter (SICOFI®-4)
PEB 2465
General Description
Type
Package
P-MQFP-64-1 (SMD)
The Signal Processing Codec Filter (PEB 2465-H), SICOFI-4
is the interface between four analog subscribers and the
digital switch. The chip combines all the circuitry needed for
encoding, decoding and PCM filtering of 4 speech channels
on CMOS chip. An integrated digital signal processor (DSP)
allows the analog line card to be adapted to the widest variety
of national specifications and applications by programming
the individual digital filter functions. A wide variety of SLlCs
(subscriber line interface circuits) can be employed and
simply adapted.
PEB 2465-H
Features
• Codec for four analog subscribers (public switch and
PBX) usable towards the trunk and the subscriber
• Specification according to relevant CCITT, EIA and
LSSGR
• IOM-2 interface
• Usable with transformer and electronic SLlCs
• DSP technology
• Adaption to different country specifications with
following programmable filters
– AC impedance matching (return loss better than 30 dB)
– transhybrid balancing (better than 30 dB)
– frequency response
– gain (steps of 0.05 dB)
• Advanced test capabilities
The SICOFI-4 can be used in both, PBXs and public
switches. The external configuration does not vary – only
decoupling capacitors are needed. Widely differing national
specifications can be met with a single hardware by just
changing the filter coefficients: Signal level, terminating
impedance, equivalent impedance, frequency response
correction and the required coding procedure (A- or µ-Law)
are simple to program. Siemens provides well proven
software for calculating the required coefficients.
• DTMF generator
• Level metering function
• Boundary scan
• Single 5-V power supply
The SICOFI-4, together with standard SLlCs, also fulfills the
new specification for idle channel noise in the out-of band
range, already demanded by Japan and Great Britain.
A flexible test concept operating at component level as well
as at system level is provided to support users in designing
and manufacturing their systems. The following test options
are integrated into the SICOFI-4:
Applications
PBXs:
• 4 analog lines for subscribers and trunks
CO:
• Interface for four analog subscribers
• BIST (built-in self test) in the digital part
• Boundary scan as per IEEE 1149.1
• Functional testing with various test loops
• Simple stimulation by two built-in DTMF (Dual Tone
Multifrequency) tone generators
• Function self test using what is known as the “level
metering function” with which not only the chip but also the
SLIC connected to it can be tested (system test).
Interfaces
• 4 × t/r interface
• IOM-2 interface
• Eight l/O signaling pins per channel
• Boundary scan
The powerful, modular IOM-2 interface implemented
on the allows minimal wiring to be used on the board and
thereby a low-cost design. A suitable controller (e.g. the
ELIC, PEB 20550-H) is used to direct the relevant
coefficients for filter programming and the required control
signals as well as the voice signals to the SICOFI-4. Signals
from the SLIC can be issued by the SICOFI-4 to the IOM-2
interface and read out under interrupt control. This
significantly reduces the load on the microcontroller.

The Signal Processing Subscriber Line Interface Codec Filter
SLICOFI is a logic continuation of the well established family
of the Siemens DSP Codec-Filter ICs with the vertical
integration of all DC-feeding, supervision and PL meterpulse
injection features on-chip as well. Fabricated in a standard
1 µm BiCMOS technology the SLICOFI is tailored for very
flexible solutions in digital communication systems. For the
first time the SLICOFI uses the benefits of a DSP not only for
the voice channel but even for line feeding and supervision
which leads to a very high flexibility without the need for
external components.

• Single chip CODEC and FILTER including all LOW
VOLTAGE SLIC functions
• Only few external components required
• No trimming or adjustments required
• Specification according to relevant CCITT, LSSGR and
DBP recommendations
Based on an advanced digital filter concept, the PEB 3065
provides excellent transmission performance. The new filter
concept leads to a maximum of independence between the
different filter blocks. Each filter block can be seen as a one
to one representative of the corresponding network element.
Together with the software package SLICOS, filter optimizing
to different applications can be done in a clear and straight
forward procedure. The AC frequency behaviour is mainly
determined by the digital filters. Using the new oversampling
1-bit Σ∆-AD/DA converter, linearity is only limited by second
order parasitic effects.
• Digital signal processing technique
• Advanced low power 1 µm BiCMOS technology
• PCM encoded digital voice transmission (A-Law or µ-Law)
• Four pin serial IOM-2 interface
• High performance A/D and D/A conversion
• Programmable digital filters for
– impedance matching
– transhybrid balancing
– frequency response
– gain
• Advanced test capabilities
– integrated line and circuit tests
– 6 digital loops
– 5 analog loops
– two programmable tone generators
• Optimized HV-SLIC interface
The new – digital – solution of line feeding offers free
programmability of feeding current and voltage as well as
very fast settling of the DC operating point after transitions. A
0.4-Hz lowpass filter in the DC loop is mainly responsible for
the system stability.
• Fully digital programmable DC characteristic
– programmable constant current from 0 – 70 mA
– programmable resistive values from 0 – 2 × 500 Ω
• Programmable integrated Teletax injection and filtering
during conversation and onhook
– programmable up to 125 mVrms (5 Vrms at a/b wire)

crossing injection
Additionally telefax generation and filtering is implemented
as well as free programmable (balanced) ring generation with
zero crossing injection. Offhook detection with
programmable thresholds is possible in all operating modes.
To reduce overall power consumption of the line card, the
SLICOFI provides a special mode called Power Denial where
offhook is done via two high voltage inputs (VLINE) directly
connected to the line since the HV-SLIC is switched off.
– programmable frequency between 16.6 and 70 Hz
– Programmable amplitude up to 2.125 Vrms (85 Vrms at
a/b wire)

ISDN High Voltage Power Controller (IHPC)
PEB 2026
General Description
Type
Package
The IHPC is an integrated power controller especially
designed for feeding two-wire ISDN-transmission lines. One
line can be powered by one IHPC. An external resistor
defines the value of the current-limit for the line. Powering
can be switched on or off by the logic inputs “PFEN” and
“PFENQ”. With a logic low at the “APFI” output the IHPC
signals that current-limiting is active; this signal is low-pass
filtered. An external capacitor defines the corner frequency of
this low-pass filter and the resulting delay time respectively. A
second external capacitor is needed to make sure that
longitudinal disturbance (AC) will not produce a current
limiting effect. Line current-limiting and reducing this limiting
level in case of overtemperature guards the IHPC against
overloads.

ISDN Layer-2 Protocol Controllers
ISDN Communications Controller (ICC)
General Description
Type
Package
While the IOM structure supports high flexibility with respect
to layer-1 of data transmission, the ISDN communications
controller can be used in all applications for link access
protocol control. This is of great importance regarding
production volume, software continuity and engineering effort
necessary for the use of the complex circuit. For further
reduction of software, high-level layer-2 support has been a
main target of circuit definition.

P-LCC-28-1 (SMD)
P-DIP-24-1 (not for new designs)
P-LCC-28-1 (SMD)
Features
• High-level support of LAPD-protocol
• FlFO-buffer (64 bytes per direction) for efficient transfer of
D-channel messages
• IOM interface compatible (IOM-1 or IOM-2)
• Standard parallel microprocessor interface
• Support of activation/deactivation procedure
• Variety of operating modes
• µP access to B-channels and IOM-intercommunication
channels
• Control of peripheral devices via IOM Monitor and C/l-
channel protocols
D-channel protocol handling is the main task of the ICC. Its
characteristic features are determined by an on-chip LAPD
controller and a sophisticated FlFO-structure. The LAPD
controller performs multiframe operation largely
autonomously with a window size of 1. All S- and l-frames,
including the address and control fields, are evaluated in the
ICC. Depending on the status of the controller, positive or
negative acknowledgements are generated without
interrupting the CPU. When the procedure is terminated, an
interrupt status is generated to inform the CPU of the status
of the procedure. To enable the ICC device to be used in
complex protocol applications with window size of up to 7, a
transparent mode is implemented. In this mode the layer-2
headers are transferred transparently to the CPU.
• 2-µm CMOS technology and low power consumption:
Standby: 2 mW
Active:
4 mW at 512 kHz
The synchronization of the 16-kbit/s D-channel with the CPU-
bus is performed by buffers with a capacity of 64 bytes per
direction. Sophisticated buffer controllers allow overlapping
input/output operation, which ensures that the maximum
packet length is not limited by the buffer size.
This feature greatly reduces the dynamic load of the
microprocessor system.

These devices are capable of switching not only the
B-channels but also the D-channel. Thus, the designer can
decide whether he wants to process D-channel signaling
information decentralized, on the line card, or pass it through
to be processed centrally.
Features
• Four independent HDLC channels
• 64-byte FIFO buffering per channel and direction
• Handling of basic HDLC functions
• Single or quad connection to serial transmission lines
• IOM- or PCM interfaces
• Programmable time-slots and channel data rates (up to
4 Mbit/s)
• Collision detection and resolution circuitry for shared
time-slots
• 8-bit parallel µP interface with vector interrupt
• Advanced low power CMOS technology: 50 mW
The IDEC has been optimized for processing the D-channel
signaling information on digital exchange line cards. Four
independent HDLC controllers have been implemented on a
single IC. Thus, one IDEC can handle the D-channels of up to
four subscriber lines.
The IDEC is based on the same core architecture as the
PEB 2070 ICC, but has been optimized for exchange line
cards and then repeated four times.

The SBC is designed to meet all CClTT requirements, and,
moreover, implements additional features necessary in
specific applications. The device contains the transceiver
function, timing recovery for the different modes of operation,
circuitry for the collision resolution function and a state
control block to handle the activation/deactivation
procedures autonomously without the support of a
microprocessor. A flexible buffer structure performs the
frame-alignment function in PBX-trunk applications, where
the system clock deviates from the central office clock
derived from the line. Matching of the actual line attenuation
is supported by receiver circuitry which contains adaptively
adjustable thresholds.

General Description
Type
Package
The most challenging requirement in ISDN is full-duplex
transmission at a data rate of 144 kbit/s over the existing
twisted-pair telephone cables (U-interface). Among several
approaches for solving this problem, ping-pong time-
compression multiplexing and echo cancellation have been
proposed as most suitable for VLSI implementation.
Moreover, echo cancellation has proven to be the best
method for public lines which typically reach lengths in the
range of 8 km.

ISDN Burst Transceiver Circuit (IBC)
PEB 2095
General Description
Type
Package
In addition to four-wire S-interface terminals, the IOM
architecture also supports two-wire terminals for PBX
applications. A survey of PBX-loop conditions demonstrates
that typically 95% of the subscriber loops show line lengths
below 2 km. Therefore, a more economical solution which is
optimized to these shorter loop lengths is required.
PEB 2095-N
PEB 2095-P
P-LCC-28-2 (SMD)
P-DIP-24-1 (not for new designs)
Features
• Half-duplex burst-mode two-wire transceiver
• 144-bit/s user bit rate (B+B+D)
• 384-kHz line clock rate including maintenance and
synchronization
A time-compression multiplex concept has been chosen
which – for separation of direction – divides the framing into
a transmit and receive section. Taking synchronization bits
and line conditions into account, a clock rate of 384 kbit/s,
twice as high as for the S-bus, has been found to be optimal
with respect to time compression, interference line
attenuation and delay. The transceiver uses AMI coding,
scrambling, automatic gain control and √f-equalizing to
obtain excellent transmission quality.
• U interface, industry standard for
P0
2-wire PBXs (AMI-line code)
• IOM-interface compatible (IOM-1 or IOM-2)
• Adaptive line equalization (SC filter)
• Recovery of clock and frame signals from data stream
• Activation/deactivation procedure according to CClTT
recommendation
• Awake in power-down mode

Overview on Primary Rate Interface (PRI)
Applications for the Primary Rate Interface include trunk lines
between public central office (CO) exchanges, from a PBX
to a CO, interlinking PBXs, the gateway connecting a LAN to
the public network on a PBX, interlinking LANs, interfacing a
large computer or data intensive terminal (e.g. CAD graphics)
with the CO or a PBX etc.
Frame alignment for all commonly used framing and
multiframing formats is performed by the ACFA. The device
synchronizes the transmit and receive signals, interfaces the
data rate from the line to the 2.048 Mbit/s or 4.096 Mbit/s
internal highway and codes/decodes one of three selectable
line codes.
Due to different technical evolutions in Europe and the US
there are two basic interface types for 1st order transmission
systems, the T1 and the CEPT or E1 standard. The ISDN-
PRI is based on these two different standards. The main
difference between ISDN-PRI and T1/CEPT transmission
systems is the type of signaling used.
For PCM24, this transmission code can be either B8ZS or
AMI-ZCS whereas for PCM30, it is always HDB3. Alarms and
error conditions are reported to the microprocessor via a
maskable interrupt line. The ACFA can also be used for
various signaling schemes. Rather than using the HSCC/
HSCX, signaling information can be handled by a less
intelligent communications controller without programmable
time-slot access. For such devices, the ACFA provides the
required signaling information via special purpose pins.
Additionally, the ACFA has a DMA interface for transferring
signaling information to/from a microprocessor controlled
memory. Finally, signaling data can be accessed directly via
the microprocessor interface.
The T1 standard is based on the PCM24 technique, where
twenty-four 64-kbit/s basic channels and one framing bit are
combined into one 1.544-Mbit/s frame format.
The CEPT standard is based on the PCM30 technique. The
2.048-Mbit/s frame consists of thirty 64-kbit/s basic channels,
one 64 kbit/s signaling channel and 64-kbit/s framing and
maintenance channel.
Siemens new generation of Primary Rate Interface
component, the PEB 2254 FALC54 (Framing And Line
Interface plus signaling Controller), implements the
functionality of a line interface, frame aligner and signaling
controller for both standards E1 and T1 on a single chip.
Siemens Semiconductor Division offers a complete solution
of ICs covering different standards and applications.
The PEB 2236 IPAT®-2 (ISDN Primary Access Transceiver)
and the PEB 2035 (Advanced CMOS Frame Aligner) fulfill
the T1 and CEPT standards. At the system side the ACFA
provides a synchronous PCM interface for connecting to
other application specific ICs (e.g. MTSx, HSCX).
Applications
In general the following applications can be covered:
• Synchronous/asynchronous multiplexers
• Digital access cross connects
• Central offices switches
• Remote switches, subscribers loop carriers
• LAN, MAN, WAN, Bridges, Routers
• FITL
The IPAT-2, together with the ACFA, implement the layer-1
physical interface.
Both devices are programmed via the µP interface to perform
the different standards, applications and maintenance/
service functions.
The IPAT-2 is a monolithic line driver for primary access lines
of either the PCM24 (T1, N. America/Japan) or PCM30
(CEPT, W. Europe) standards. In the receive direction, the
device recovers the clock and data signals from the line and
forwards them to the ACFA.
• PBX interfaces
The following chapter outlines the application of the Primary
Rate devices ACFA, FALC54 and I PAT-2 and shows the
flexibility of the architecture.
The IPAT-2 is transparent to the received line code. In the
transmit direction, the device takes the signal received from
the ACFA and forms it into transmission pulses according to
CCITT recommendations for the PCM30 or AT&Ts DMI
specifications for PCM24. Correspondingly, input/output jitter
requirements comply with both CCITT and
In the switching application the Primary Rate Interface is
connected to a switching network of a PBX, CO or
concentrator. The switching devices MTSL (Memory Time
Switch Large), MTSC (Memory Time Switch CMOS) and
MTSS (Memory Time Switch Small) perform the switching
and data rate adaption. In addition to the switching function
the MUSAC (Multipoint Switching and Conferencing) can
handle 64-conference channels in any combination.

Overview on Switching, Attenuation and Conferencing IC-Family
Supervision and control of the entire system, including
connection set-up, maintenance and testing, is performed
in a powerful central processing unit. Besides this, the
through-switching of PCM channels is done in a switching
network unit, whereas the tasks of a frame alignment unit are
to interface PCM transmission routes with the switching
system.
In a digital switching matrix one distinguishes between two
basic switching principles:
• Time division multiplex
• Space division multiplex
A method that is frequently used involves a combination of
the two principles, this being called space/time division
multiplex. The figure illustrates the different principles.
Digital exchanges put calls through by newly arranging the
speech signals coded with 8-bit words (PCM time-slots). The
code words are transmitted serially on PCM lines. The
sampling frequency of 8 kHz produces PCM frames with a
duration of 125 µs. The transmission rate on the line
determines how many code words (speech channels) can be
accommodated within a sampling period. With a data rate of
2048 kbit/s for example, there are 32 time-slots of 8 bits each.
Four lines with a data rate of 8192 kbit/s have a transmission
capacity of 512 channels.
In time division multiplex only the time-slot is altered during
switching. All signals from a certain input PCM line are
switched to a fixed output line, only the time-slot sequence
may change.
In space division multiplex incoming PCM data are only
rearranged in space. The input time-slot equals the output
time-slot. However, input from one PCM line can be switched
to different output lines.

or “Fractional” T1. 64 kbit/s time-slots are combined for
An additional future requirement is wideband switching. In
contrast to voice switching, wideband switching is
optimized for data transmission, e.g. for ISDN H-channels
higher data rates. As a precondition all switched time-slots
have to be output in the same frame. For example
6 time-slots could be combined to a 384-kbit/s bundle.

MTSC
MTSL/MTSL-16
Siemens Semiconductor offers devices which take into
consideration the needs for efficient realization of these
tasks. One of the switching network circuits offered is the
Memory Time Switch in CMOS (MTSC) PEB 2045, which
has the ability to connect any of 512 incoming PCM
channels to any of 256 outgoing PCM channels on a single
chip. A non-blocking switch for 512 time-slots can be built up
with two devices only. A further expansion can be realized
very easily too. Different kinds of operation modes enable the
use of the MTSC PEB 2045 in 2048 Mbit/s, 4096 Mbit/s and
8192 Mbit/s or mixed PCM systems.
The largest in our family, the Memory Time Switch Large
(MTSL) PEB 2047 is capable of switching up to 1024
time-slots.
The MTSL allows the switching of fractional T1 and data
bundles. The MTSL-16 is a selection for 16-MHz
applications.

conferencing, the Multipoint Switching And Conferencing
Unit (MUSAC) PEB 2245, which performs the complete
switching functions of the MTSC, and has a signal processor
for handling up to 64 conferencing channels in any
combination. The input and output channels can also be
attenuated individually to achieve best transmission quality.
As an additional feature the MTSC PEB 2045 together with
an Advanced CMOS Frame Aligner (ACFA) PEB 2035 can
realize the system interface of up to four primary multiplex
access lines.

The PCM information for a complete frame is stored in the
4-Kbit speech memory SM, i.e. all of the 512 words with 8 bits
are written into a fixed position of the SM. This is controlled
by the input counter every 125 µs. The words are read using
random access with an address that is stored in a connection
memory CM for each of the 256 output channels. The access
to the CM is controlled by the output counter.

Package
The MTSS PEB 2046 is a monolithic CMOS device which
has the ability to connect any of the 256 PCM channels of
eight incoming PCM lines to any of the 256 PCM channels of
eight output lines.

The input information of a complete frame is stored in the
speech memory SM. The incoming 256 channels
of 8 bits each are written in sequence into fixed positions in
the SM. This is controlled by the input counter in the timing
control block with an 8-kHz repetition rate.
Features
• Time/space switch for 2.048-kbit/s PCM systems
• Switching of up to 256 incoming PCM channels to up to
256 outgoing PCM channels
• Eight input and eight output PCM lines
• Configurable for a 4096- and 8192-kHz device clock
• Tristate function for further expansion and tandem
operation
• 8-bit µP-interface
• Single +5-V power supply
• Advanced low power CMOS technology
For output, the connection memory (CM) is read in sequence.
Each location in CM points to a location in the speech
memory. The byte in this speech memory location is read into
the current output time-slot. The read access of the CM is
controlled by the output counter which also resides in the
timing control block.
Thus the CM needs to be programmed beforehand for the
desired connection. The CM address corresponds to one
particular output time-slot and line number. The contents of
this CM-address point to a particular input time-slot and line
number (now resident in the SM).

Memory Time Switch Large (MTSL)
PEB 2047
General Description
microprocessor command. As a result the input countervalue
on the rising edge of the FS signal can be read from an
internal register. Thus delay compensation is easily
managed by programming appropriate clock shift values
and/or a possible software offset.
The MTSL PEB 2047 is a memory time switch device.
Operating with a device clock of 4096 kHz or 8192 kHz it can
connect any of 1024 PCM-input channels to any of 512
output channels.
During operation of the chip, a frame length check, which
controls correct synchronization by the SP pulse and
generates an interrupt in case of lost or achieved
synchronization is also supplied.
The input information of a complete frame is stored
in the on-chip 8-kbit data memory DM. The incoming
1024 channels of 8 bits each are written in sequence into
fixed positions in the DM. This is controlled by the input
counter in the timing control block with an 8-kHz repetition
rate.
The standard 8-bit µP interface can communicate with Intel
multiplexed/demultiplexed microprocessors as well as with
Motorola demultiplexed processors. It gives access to the
internal registers and to the control – and data memory. Five
directly addressable registers are provided. All other
registers and the memories are accessed by a simple three
byte indirect access method (similar to the MTSC PEB 2045).
For outputting, the connection memory (CM) is read in
sequence. Each location in CM points to a location in the data
memory. The byte in this data memory location is transferred
into the current output time-slot. The read access of the CM
is controlled by an output counter.
The switching path of the MTSL including input buffer, data
memory, control memory, output buffer and timing control
can be tested in the system by a built-in selftest. After
activating this mechanism it takes 1.25 ms (8192 kHz) until
the result “selftest ok/selftest not ok” can be read from the
internal status register.
The synchronization of this procedure will be achieved by a
rising edge of the synchronizing pulse SP, which is always
sampled with the falling edge of the device clock.
Different modes of operation are configurable at the PCM-
input interface. Also, 8 PCM-input lines can be synchronized
with individual clock shift values to compensate different line
delays. If more than 8 inputs are used one clock shift value
controls up to two ports at the same time.
After test completion the control-memory is also reset.
In applications where 64-kbit/s channels are combined for
higher data rates (e.g. ISDN H-channels) the MTSL ensures
that all switched time-slots are output in the same frame.
The input lines IN8 to IN15 can be used as additional
frame-synchronization inputs FS. After synchronizing the
device by the SP pulse, the FS inputs can be evaluated on a
per port basis. This evaluation procedure is started by a
In voice applications where a low delay is important, the
MTSL can be programmed for minimized switching delays.

A World of Applications
Data communication has gained a key role in modern
computer systems. We are on the threshold of an era of total
communication: every (micro)computer unit has to be able to
communicate with other devices – either in synchronous or
asynchronous data transmission mode.
Office Automation and
Wide Area Networks (WAN)
Typical ESCC2 (Enhanced Serial Communication Controller
with 2 channels, SAB 82532) applications are
communication boards for workstations and minicomputers
as well as l/O multiplexers, bridges and gateways (X.24,
PRI). ESCC2 can be used for nearly all applications from
terminal adaptors and fast HDLC links to Primary Rate
Interfaces (T1/S2) or ISDN interfaces (SO); using unique
software.
Let us have a look at this rapidly growing world of many
different applications. There are among others the following
applications: telecom, office automation, traffic control,
medical equipment, and factory automation.
Telecom
If the designer requires multichannel access, he can save a
tremendous amount of board space by using the highly
integrated eight-channel multiprotocol controller SAB 82538
(ESCC8): four ESCC2s (eight serial channels) in one
package.
Todays telephone and telecommunication equipment is
getting more and more digitalized while the older analog units
are being replaced. This means that analog signals are
converted to digital data as soon as possible before being
transferred and processed. Back-conversion is made as late
as possible. Consequently the amount of transferred data in
telecom applications is increasing tremendously. Depending
on the desired data throughput and transmission mode, the
designer always gets the right choice with serial
communication ICs from Siemens. There are a lot of goals to
be met: transfer control by high level transportation protocols,
transmitting and receiving data pockets, time-division
multiplexing in time-slot systems, handling of different data
encoding/decoding schemes, etc.
Fast LANs
If clock recovery up to 4 Mbit/s is needed (e.g. in fiberoptic
transmission systems), the designer can use ESCC2
(Enhanced Serial Communications Controller, SAB 82532).
Basically, the ESCC2 is a faster 16-bit HSCX with a big
bundle of extra functions. HDLC-data transfer can be
implemented up to 10 Mbit/s. ESCC2 is a multiprotocol
controller which enables designers to use synchronous,
bisynchronous as well as asynchronous, fast data transfer
with one chip on one software basis.
All these kinds of data transfer can be managed by
SAB 82525 or SAB 82526. These ICs are called High-Level
Serial Communication Controllers Extended (HSCX,
SAB 82525) and Single-Channel High-Level Serial
Communication Controllers Extended (HSCX1, SAB 82526).
They were especially designed for serial communication
interfaces in telecom networks requiring HDLC based
protocols.
Typical HSCX applications are network communication
boards, central D-channel signaling, DMI boards, data-link
controllers in digital mobile radio networks as well as cordless
telephone sets.

Siemens’ family of serial communication controllers
ESCC2
comprises a full range of different ICs. While each of them is
designed to enhanced particular features, together they
compose a wide profile of performance. Thus, most likely our
family of complementary devices offers an ideal solution to
many applications in serial data communications.
The Enhanced Serial Communications Controller (ESCC2) is
a multiprotocol controller offering an extraordinary profile of
protocol options at a high-speed transfer rate of up to
10 Mbit/s for each of its two independent channels.
ESCC2 was developed for the different communication
requirements of wide area network, local area network, small
area network and proprietary network applications.
HSCX
The High-Level Serial Communications Controller Extended
(HSCX) supports a number of synchronous standardized
protocols and a greater number of proprietary protocols at a
transfer rate of up to 4 Mbit/s. Each of its two channels works
independent of the other. Its specific fields of application are
proprietary HDLC local area networks (LAN).
The result is a communications controller as a standard for
implementing Open System Interconnection (OSI) layers-1
and -2 in all these applications. This fact noticeably reduces
development and system costs.
The board space, for example, is reduced by on-chip collision
detection and resolution, programmable preamble, clock
recovery, the logic for multiple protocols and multiple
encodings, 16- and 32-bit CRC, time-slot, assignment,
queued interrupt status for all important events like receiver
FIFO full, receiver FIFO overrun and end of frame
transmission.
HSCX 1
The Single-Channel High-Level Serial Communications
Controller Extended (HSCX1) is the single channel version of
HSCX.

designed for use in fractional T1 interfaces as well as for
applications in switching systems.
ADMA
Less system cost, less development cost, less board
space, less power consumption and high performance in a
proven 1-µm CMOS technology are what you gain by using
this communication genius as a standard for all your
applications.
The Advanced DMA Controller (ADMA) is a four channel l/O
coprocessor that is optimized to handle data transfers in
either 8-, 16- or 32-bit microprocessor systems. It can
transfer up to 40 Mbytes of data per second in a 20-MHz
system. The ADMA transfers data using single cycle, two
cycle and 32-bit fly by operations and can gather or scatter
data with efficient linked list data chaining, making it one of
the most versatile DMA controllers available today. A smaller,
reduced cost version of the ADMA (SAB 82C257) is also
available.
The following ICs are in development or under definition and
will be available in due time to offer new attractive solutions
for serial communication control.
ESCC8
The eight-channel Enhanced Serial Communications
Controller (ESCC8) offers eight independent serial channels.
Basically it consists of four ESCC2 cores. It is a very suitable
solution for multiprotocol and multichannel applications.
ASCC8
The ASCC8 is an eight-channel Universal Asynchronous
Receiver/Transmitter (UART). It is optimized to handle eight
high-speed asynchronous channels at rates of up to 2 Mbit/s
in 16-×-oversampling mode. The ASCC8 is ideally suited for
applications that include card-to-card signaling MODEM
pools, asynchronous routers, and simple high speed
point-to-point communications between processing elements
within a large system.

Asynchronous Transfer Mode (ATM) ICs
Introduction
Traditional telecommunication structures are based on Time
Division Multiplexing (TDM), offering fixed-bandwidth time-
slots. ATM however sends data only when required, i.e.
frames are sent asynchronously. By packing the information
in 53-byte cells, including a 5-byte header containing the
destination address, data is guided through the network
along virtual paths and channels. ATM offers bandwidth on
demand with highspeed transmission ranging from kilobytes
up to gigabytes per second.
In the last few years, Asynchronous Transfer Mode (ATM)
has made big leaps towards standardization and
practicability.
Acceptance in the market is high, due to the future need of
highspeed networking and seamless internetworking. This
new technology perfectly suits these market demands. ATM
networks offer bandwidth on demand, thus being capable of
matching the user’s data needs from sporadic high-
bandwidth bursts to isochronous constant-bandwidth. ATM
technology offers high-speed networks with various
bandwidths and works with any type of transmission
infrastructure. The very flexible basic structure allows to build
and interconnect high-speed WANs, corporate WANs/MANs,
backbone LANs, or powerful links to desktop terminals.
Siemens Semiconductor Group addresses the market’s
demand for this kind of network technology by being a driving
force in the standardization activities and providing a
complete ATM chipset to the market. ATM-system designers
are supported by a family of Siemens ATM devices to build all
kind of ATM applications. This ranges from dedicated ICs for
Network or Line Interface Cards to powerful ATM switches
and transmission devices.

Asynchronous Transfer Mode (ATM) ICs
Building Seamless ATM Networks
ATM technology is capable of providing powerful networks
for various needs. Such an application could be a large
campus network, just as shown in the figure below. In this
example, several backbone switches, located at different
places, are linked together. However, ATM allows this
network to be managed centrally, since all backbone
switches are configured to logically constitute one single
switch. Workgroups are connected to the backbone via ATM
workgroup switches.
The functionality of the Siemens ATM chipset, such as the
cross connect feature of the ATM-Switching Matrix
PXB 4310, allows members of the same workgroups to
communicate effectively with each other without occupying
the backbone. Only two devices of the Siemens ATM chipset
are required to develop ATM-Network Interface Cards for
PCs and WS, providing seamless access to the network.

Asynchronous Transfer Mode (ATM) ICs
ATM-Application Examples
ATM-Workgroup Switch
Instead of using a hub to connect a small number of
computers (workgroup), an ATM-work group switch can be
applied. Data transmission to the computers is handled by
transceiver devices, such as the PXB 4230 for unshielded
twisted pair lines, or PXB 4240 for SDH/SONET lines. The
actual switching function is performed by the ATM-Switching
Matrix (ASM) PXB 4310.
This cell switch features 32 inputs and 16 outputs with cross
connect functionality. The ASM chip is designed to a special
cell format, in order to reduce the pin count and power
dissipation. Up-stream and down-stream conversion from the
standard 53-byte ATM-cell format to this Siemens proprietary
format SLIF (Switch Link Interface) is performed by the ASP
chipset PXB 43201 and PXB 43202.

PCM Codec Filter for Analog Line Cards
in Digital Communication Systems
Todays highly complex system development projects make it
necessary to have a powerful development environment
available additionally to the components themselves.
The Siemens PCM Codec Filter are fully integrated PCM
CODEC and Filter in advanced low power CMOS technology
for applications in digital communication systems.
Some of the necessary tools are supplied by the chip
manufacturer himself.
Based on a digital signal processing technique
programmable digital filters adapt the transmission behaviour
especially for AC impedance matching transhybrid balancing
frequency response and gain.
The tools consist of either component evaluation boards or
sometimes even almost ready to copy system designs. Also
software chip drivers are often supplied to ease the
integration of components into a customer’s software design.
In some cases software skeleton solutions or even ready to
use software is supplied to speed up the whole system
design.
For analog line card designs in digital communication
systems a family of Siemens Codec-Filter ICs can be
offered:
Besides the tools supplied by the silicon vendor a lot of third
party tools are available on the market which can efficiently
be used. The support tools supplied by Siemens are typically
designed to be used in conjunction with a PC and third party
software tools giving a very powerful environment.

Tools for ISDN Basis Rate Line Card Designs
U Transceiver Development Tool (2B1Q)
The IEC-Q Reference Board interfaces ISDN transmission
lines and terminal areas providing echo cancellation and
message recovery using digital techniques. Hence the main
use of the IEC-Q Reference Board is to accomplish
performance measurements i.e. bit error rate (BER)
measurements on the ETSI and ANSI defined loops.
2.1
Together with the SIPB 5121 Line Card Module the IEC-Q
Reference Board SIPB 2091 constitutes the layer-1
functionally needed for the evaluation of various digital line
card architectures using 2B1Q technique for interfacing with
the U-reference point.
The optimized layout of the Reference Board allows for
performance measurements in all operation modes available
with the IEC-Q. The so called hybrid was developed to reach
optimum loop lengths and to cover all 15 ANSI loops as well
as the 8 ETSI defined loops. The figure below shows a typical
configuration with LT and NT 1 where the interconnection
between the two U-transceiver devices is established with
means of a dual lead copper wire (U).
2.2
Introduction to the IEC-Q Reference Board
SIPB 2091, SIPB 2092 and SIPB 2092-H
The IEC-Q Reference Board was developed to demonstrate
the performance of the Siemens IEC-Q (PEB 2091)
U-interface transceiver IC. The IEC-Q (ISDN Echo
Cancellation Circuit) uses 2B1Q code for transmission on U.
A single board can be configured by the user to suit multiple
operation modes such as LT and NT modes. Test points
allow for comfortable monitoring of relevant signals. This
enables the developer to quickly comprehend both the
IC- and U-interface-related signals.
The SIPB 2092 additionally supports the stand-alone
(IOM-2) mode and the µP-interface mode. SIPB 2092-H is
identical to SIPB 2092 except that a P-TQFP-64 package
socket instead of a P-LCC-44 socket is provided. For stand-
alone operation of the IEC-Q, both SIPB 2091 and SIPB 2092
are equally suited.

Bit-Error-Rate Measurement
with SIPB 5000 Main Board
The configuration below describes the use of standard LT/NT
applications for the purpose of BER measurements when
supplemented with two BEAM modules. The figure shows
the complete SIPB system set-up for a BER measurement in
LT-NT direction.
For bit-error-rate (BER) measurements on U the following
add-on modules are required on the LT side in addition to the
LT IEC-Q Reference Board:
ISDN Terminal Adaptor Module (ITAC ) SIPB 5140
LAYER-2 Module SIPB 5120-2
Comments:
For the bit-error-rate measurement the LT is configured in the
LT-512-kHz mode since the BEAM module only supports a
512-kHz-DCL clock rate.
Bit Error Adaptor Module (BEAM) SIPB 5312
The following modules are required for BER measurement
on the NT side in addition to the NT IEC-Q Reference Board:
With means of the two BEAM modules the BER test
equipment can be synchronized to the IOM clock rate as well
as insert and extract B1/B2 channel data via IOM. BER
measurement is then accomplished by comparing the
inserted with the extracted data. A line simulator is used for
emulating lines and loops including NEXT noise impairments
in order to run performance tests according to the relevant
specifications (ETSI/ANSI).

The Different Steps in Development
Designing the Hardware
The ISDN Telephone Development Board SIPB 8051 is a
more or less ready to copy environment to demonstrate the
terminal system in silicon using the ARCOFI-SP (PSB 2163),
the ISAC-S TE (PSB 2186) and the one-chip controller
SAB 80515 with the ISDN protocol software. An ITAC
(PSB 2110) for the rate adaption as well as an ISAC-P TE
3.2.1
The SIPB 5000 system can be used as a platform for all
development steps. In a later stage it is of course necessary
to make a cost optimized design. For this a subset of the
board design can be used. All the wiring diagrams are
shipped with the board to speed up this process.
(PSB 2196) for the U interface is also onboard.
PN
To set up a development environment for serious
developments it is best to use both an SlPB 7011A kit as a
network terminator being able to simulate the public ISDN
and secondly an SIPB 8051 system as the real development
platform. Both systems should be connected and of course a
PC should be connected to the SIPB 8051 to run a
C-Compiler and to download and debug code.
3.2.2
Developing the Software
In a premature stage of a development it is very useful to
verify the design by running program sequences on a similar
hardware platform. To manage this task Siemens offers a
very comfortable menu-driven testing and debugging
software. The package delivered with the userboard allows a
direct access to the chip registers by symbolic names.
Subsequent accesses may be written to a file and run as a
trackfile.
The Keil C51 professional package (in USA Franklin C51
package) as well as the development package of the
Swedish company lAR Systems (in USA Archimedes) have
been used with the SIPB 8051. Their high level language
debuggers can be used very efficiently with the SlPB 8051.
Example trackfiles for different configurations are delivered in
the package and will be a great help to the user in getting
started and to speed up his software development.
Both systems should be connected and an 8051 type
C-Compiler and high level language debugger should be
available. Additionally the IOS software should be used as a
very efficient software platform if a public protocol is required.
This software is a very compact software solution. It fits on a
one chip controller without needing additional memory. For
rapid prototyping or PTT approval an E2PROM version of the
80C515A is also available.

Figuring out the ARCOFI -SP Coefficients
for Speakerphone
4.2.1
Siemens Semiconductor Group offers two dedicated,
DSP-based speakerphone realizations ARCOFI-SP
PSB 2165 and PSB 2163.
The SIPB 8051 can be used as a platform for all development
steps. In a later stage it is of course necessary to do a cost
optimized design. For this a subset of the SIPB 8051 design
can be used. All the wiring diagrams are shipped with the
board to speed this process up.
The first digital speakerphone support was implemented in
the ARCOFI-SP PSB 2165, which already exists since 1991.
A substantial feature of the ARCOFl-SP is to provide means
for minimizing feedback in electrical loops and to
compensate for acoustical couplings. Therefore ARCOFI-SP
offers 23 parameters which are set by software
4.2.2
Developing the Protocol Software
A major task in the design work is the development of the
public ISDN protocol software. To ease this work Siemens
provides the IOS as an almost ready to copy protocol
software kernel. IOS has been designed in C and it can be
ported in nearly all CPU environments. For the development
of ISDN phones or TAs IOS has been ported onto an
80C515. Still it might be necessary to do some modifications
or more likely add some features. The board can immediately
load code but the use of a high level debugger like the Keil
(FRANKLIN) TS51 or the IAR (ARCHIMEDES) C-SPY is
recommended. After loading the target system Monitor down
to the board the debuggers work perfectly. An emulator is
really not required.
programming. No further external components or trimming
are required. This half-duplex mode is based on a two point
speech detection, which controls the mode switching within
125 µs.
The speakerphone support of the new ARCOFI-SP
PSB 2163 is based on a “Stronger-Wins” algorithm. Two
speech comparators, one at the acoustic (AE) and one at the
line side (LE), mainly control the switching from one active
mode to another one. They compare permanently the signal
levels of both signal paths and control the influences caused
by the echoes at the acoustic side and at the line side. Once,
a speech detector has detected speech activity, the
comparator switches immediately to the direction where the
speech signal is louder than the other one plus the returned
echo.
This offers the advantage of a completely separate
programming of the sensitivity and of the echo control. The
sensitivity is adjusted by the speech detectors and the
speech comparators control the different feedback paths at
the acoustic side and at the line side.

The ARCOFI -SP allows the control of electrical
feedbacks. It is recommended, however, to have the
majority of the acoustic couplings minimized before, by
an optimum design of the telephone case.
Hardware Development
GOLDplus Evaluation System
The Siemens GOLDplus evaluation system comprises all
parts of a GSM full rate and half rate handset. It consists
mainly of the GOLDplusX GSM baseband board and the
GOLDplus GSM RF board as shown in figure 1.
For both ARCOFI-SPs there is very comfortable coefficient
software called ARCOS-SP PLUS which eases and reduces
any optimizations to just a simple task at the PC.
Thanks to the DSP realization, the main operational functions
are all parameterized. This technique offers a high level of
flexibility and reproducibility. An enormous advantage is the
reduction of the optimization time. With a special adaptor1) it
is possible to optimize the speakerphone system using just
one link. The iterated procedure of “Building-up a line →
Testing → Deactivating the link → Opening the telephone
case → Resoldering some RC elements → Closing the case”
is reduced to a comfortable computer session focusing on the
real work: the optimization of the switching behaviour. The
speakerphone maintenance/test function of the ARCOFI-SP
supports the transparency of these modes which are
mentioned above (refer to Application Hints for ARCOFI-SP
Users).
On the GOLDplusX baseband board all Siemens GOLDplus
baseband devices are located including the system controller
GOLD-µC (PMB 2706), the signal processor GOLD-SP
(PMB 2707), the digital-to-analog conversion device GAIM
(PMB 2905) and optionally the half-rate coprocessor
GOLD-SX (PMB 2708). All required memory devices like
FLASH memory and RAM are also found on this board.
Suitable periphery like LCD display and keypad complete the
system to a fully functional handset. The connector to the RF
board carries all baseband I- and Q-signals in both receive
and transmit direction and all RF-control signals from
GOLD-µC.
On the GOLDplus GSM RF board all the Siemens GSM RF
devices are located including the transmitter PMB 2240, the
receiver PMB 2405, the PLL PMB 2307 and the power
amplifier consisting of CGY 92 and CGY 120.
1) Refer to the application Note “Adaptor to program
ARCOS-SP in customer hardware with Siemens ISDN
PC User Board and ARCOS-SP PLUS”
The GOLDplus demo system permits evaluation of all
features of the GOLDplus chip set, both for the baseband as
well as the RF part. By adding the PMB 2708 half-rate
coprocessor the baseband may be upgraded optionally to
half-rate operation. Critical parameters like power
consumption or equalizer performance can be measured.
Cost estimations for a customer handset can be based upon
the bill of materials of the board.

Tools for GSM Telephone Designs
5.1
A Typical GOLDplus Development Environment
The development of a GSM handset splits up into
development of GSM hardware and GSM software. Up to a
certain stage development will run in parallel converging
more and more prior to GSM type approval. Hardware
development splits up into development of the baseband part
and the RF part with the RF part requiring considerable
experience and know-how.
GOLDplusX Baseband Board
Software Development Platform
GOLDplusX board permits the customer getting started
immediately with his GSM software development without
having to wait for his own board prototypes. It provides an
optimum debugging platform not only for the GOLD-µC C166
system controller but also for the DSP cores if customer
specific features have to be implemented in DSP firmware.
Siemens along with its partners offers support for all stages
of both hardware and software development permitting even
newcomers to the GSM arena to get started quickly. For
application of the GOLDplus chip set Siemens offers local as
well as central support from headquarters in Munich. UK
based Symbionics offers development of a complete GSM
hardware according to customer requirements. For
development of the RF hardware they build upon their
profound RF experience. Munich based OPTIMAY offers
mature GSM software with an easily customizable MMI.
Besides getting quickly acquainted with the baseband
functionality the board permits easy and complete control of
the RF-chip set using the GOLD-µC controller functions. This
is especially useful for evaluation and fine tuning of the
RF-board functionality.
The development of a GSM handset requires both optimum
hardware and software development tools to meet time
scales in a rapidly moving market.

Development Steps
6.1
A typical Development Environment
for a DECT-Home System
6.2.1
Designing the Hardware
In order to speed up this process, all the wiring diagrams are
shipped with the boards. Major parts of the hardware shipped
can of course be used for the final design. This is especially
true for the SWUD 1300 RF board. The SWUD 3020E or
SWUD 3025 board respectively has of course to be replaced
by the PMB 2720X or PMB 2725X chip along with the
E2PROM and the PMB 2920 chips. However, their
interconnection can be taken from of the shipped wiring
diagrams of the SWUD board.
For DECT-home system development projects, there is a
complete hardware and software solution available, which
was designed to provide a first prototype to the customer. It
actually covers all the necessary functional blocks and is fully
operational, when connected to an analog telephone
network.
The effort was made in order to speed up the development of
a DECT-home system and to provide a system hardware for
immediate software development. Besides the tremendous
know how, especially on the RF part, which is necessary for
designing DECT phones, it is now the first time that a
european standard protocol has to be matched. The DECT
standard actually defines a very complex layered protocol.
To implement that standard, a tremendous software
development effort has to be made. This part of a DECT
project is considered to be done in parallel to the final
hardware design. The DECT-user board system provides a
hardware development platform today which allows
The SWUD 1100 board will typically need to be customized
because it is very likely that one wants to use a different
keyboard layout or a customized display etc.
The major parts of the SWUD 1200 board can again be used
to design a real base station telephone line interface.
6.2.2
Developing the Software
A major task in the design work is the development of the
DECT-protocol software. The effort is considered to be
several man years. The SWUD 3500 setup is designed to
support software development projects. The memory layout
has been designed in close cooperation with Compiler and
Debugger suppliers, with the result that C51 Debuggers can
run in this environment.

The board can immediately load software, but the use of a
high-level language debugger like the Keil (Franklin) TS51 is
recommended. The monitor program of this third party
software package is already shipped with the board to get
user started more quickly. For most of the software
debugging, an emulator is not really required. But in addition
to the described software monitoring by a software debugger,
there is also a hardware emulator available from Kleinhenz
Electronic. It seems to be a good approach to use the
software debugger for most of the daily work, but to have one
emulator available for tricky real-time debugging and for final
target system software implementations.

Tools for Universal RF Circuit Designs
For the various RF circuits there are test boards available for
evaluation. For distinct applications like the DECT-system-
oriented family of user boards a complete RF application has
been put together to complete the baseband tool set as a
system solution.
Besides hardware, there is also code available to support the
development. There is a low level device driver software
available which controls the chips.
In addition to that, the source code package PRODECT adds
a complete software implementation for a typical home
system. This includes all the layers and saves the above-
mentioned several man years. PRODECT is marketed as a
one time buy out license. It implements the complete DECT
standard, and by using PRODECT the customer’s software
effort is decreased to about 10% for customized
modifications.

spätere Verarbeitung bezogen werden, um die
Machbarkeit und Wirtschaftlichkeit sicherzustellen.
Packaging is becoming increasingly important as a
consequence of larger chips and higher operating
frequencies, not only for the semiconductor
manufacturer but specifically for processors and
customers confronted with a steadily growing variety
of packages with regard to pin count, pin raster and
package sizes. For this reason, product selection
should involve not just the chip but also the packages
and, consequently, subsequent processing in order
to ensure feasibility and economy
Das Einführungskapitel behandelt die weltweite
Gehäusestruktur und deren Trend für die Zukunft und
die sich aus der zunehmenden Diversifizierung an
Gehäusen ergebende Problematik für den
Verarbeiter.
The opening section deals with the worldwide pattern
of packages and their future trend, while special
mention is made of the problems facing processors
as a result of increasing package diversification.
Die Kapitel 2 bis 4 behandeln detailliert
Abmessungen, Kenngrößen und Beschriftungen der
typischen Gehäuse des Bereichs Halbleiter
Sections 2 to 4 present a detailed discussion of
dimensions, characteristics, and markings of typical
packages from the Semiconductor Group.
Der Verpackung haben wir wegen ihrer steigenden
Bedeutung als Bindeglied zwischen
Halbleiterhersteller und Verarbeiter ein eigenes
Kapitel (5) gewidmet.
In view of its rising importance as a link between the
manufacturer of semiconductors and their processors
a whole chapter (5) has been devoted to packing.
Nützliche Hinweise zur Verarbeitung von
Bauelementen enthält Kapitel 6. Die einzelnen
Prozeßschritte werden beschrieben und die Vor- und
Nachteile der unterschiedlichen Verfahren diskutiert.
Auf die Verarbeitung feuchteempfindlicher ICs sowie
auf elektrostatisch gefährdeter Bauelemente ESD
wird gesondert eingegangen .
Useful advice on processing devices is contained in
Section 6. The different process stages are
described, and the pros and cons of the different
methods are discussed. Special mention is made of
processing humidity-sensitive ICs and anti-ESD
measures.
