Data Sheet
Overview
The CE6313 is a QPSK/BPSK 1 - 45 MSps demodulator and channel decoder for digital satellite television
transmissions compliant to both DVB-S and DSS standards and other systems, such as LMDS, that use the same
architecture.
A Command Driven Control (CDC) system is provided making the CE6313 very simple to program. After the tuner
has been programmed to the required frequency to acquire a DVB transmission, the CE6313 requires a minimum
of five registers to be written.
The CE6313 provides a monitor of bit error rate after the QPSK module and also after the Viterbi module. For
receiver installation, a high speed scan or 'blind search' mode is available. This allows all signals from a given
satellite to be evaluated for frequency, symbol rate and convolutional coding scheme. The phase of the IQ signals
can be automatically determined.
Full DiSEqC is provided for both writing and reading DiSEqC messages. Storage in registers for up to eight data
bytes sent and eight data bytes received is provided.

2.0 Functional Overview
2.1 Introduction
CE6313 is a single-chip variable rate digital QPSK/BPSK satellite demodulator and channel decoder. The CE6313
accepts base-band in-phase and quadrature analogue signals and delivers an MPEG or DSS packet data stream.
Digital filtering in CE6313 removes the need for programmable external anti-alias filtering for all symbol rates from
1 - 45 MSps. Frequency, timing and carrier phase recovery are all digital and the only feed-back to the analogue
front-end is for automatic gain control. The digital phase recovery loop enables very fine bandwidth control that is
needed to overcome performance degradation due to phase and thermal noise.
All acquisition algorithms are built into the CE6313 controller. The CE6313 can be operated in a Command Driven
Control (CDC) mode by specifying the symbol rate and Viterbi code rate. There is also a provision for a search for
unknown symbol rates and Viterbi code rates.
2.2 Analogue-to-Digital Converter
The A/D converters sample single-ended or differential analogue inputs and consist of a dual ADC and circuitry to
provide improved SiNaD (Signal-Noise and Distortion) and channel matching.
The fixed rate sampling clock is provided on-chip using a programmable PLL needing only a low cost 10 to 16 MHz
crystal. Different crystal frequencies can be combined with different PLL ratios, depending on the maximum symbol
rate, allowing a very flexible approach to clock generation. An external clock signal in the range 4 to 16 MHz can
also be used as the master clock.
2.3 QPSK Demodulator
The demodulator in the CE6313 consists of signal amplitude offset compensation, frequency offset compensation,
decimation filtering, carrier recovery, symbol recovery and matched filtering. The decimation filters give continuous
operation from 2 Mbps to 90 Mbps allowing one receiver to cover the needs of the consumer market as well as the
single carrier per channel (SCPC) market with the same components without compromising performance, that is,
the channel reception is within 0.5 dB from theory. For a given symbol rate, control algorithms on the chip detect the
number of decimation stages needed and switch them in automatically.
The frequency offset compensation circuitry is capable of tracking out up to ±22.5 MHz frequency offset. This
allows the system to cope with relatively large frequency uncertainties introduced by the Low Noise Block (LNB).
Full control of the LNB is provided by the DiSEqC outputs from the CE6313. Horizontal/vertical polarization and an
instruction modulated 22 kHz signal are available under register control. All DiSEqC functions are implemented on
the CE6313. An internal state machine that handles all the demodulator functions controls the signal tracking and
acquisition. Various preset modes are available as well as blind acquisition where the receiver has no prior
knowledge of the received signal. Fast acquisition algorithms have been provided for low symbol rate applications.
Full interactive control of the acquisition function is possible for debug purposes. In the event of a signal fade or a
cycle slip, the QPSK demodulator allows sufficient time for the FEC to reacquire lock, for example, via a phase
rotation in the Viterbi decoder. This is to minimize the loss of signal due to the signal fade. Only if the FEC fails to
re-acquire lock for a long period (which is programmable) the QPSK will try to re-acquire the signal.
The matched filter is a root-raised-cosine filter with either 0.20 or 0.35 roll-off, compliant with DSS and DVB
standards. Although not a part of the DVB standard, CE6313 allows a roll-off of 0.20 to be used with other DVB
parameters. An AGC signal is provided to control the signal levels in the tuner section of the receiver and ensure
the signal level fed to the CE6313 is set at an optimal value under all reception conditions.
The CE6313 provides comprehensive information on the input signal and the state of the various parts of the
device. This information includes signal to noise ratio (SNR), signal level, AGC lock, timing and carrier lock signals.
A maskable interrupt output is available to inform the host controller when events occur.

2.4 Forward Error Correction
The CE6313 contains FEC blocks to enable error correction for DVB-S and DSS transmissions. The Viterbi
decoder block can decode the convolutional code with rates 1/2, 2/3, 3/4, 5/6, 6/7 or 7/8. The block features
automatic synchronization, automatic spectral inversion resolution and automatic code rate detection. The trace
back depth of 128 provides better performance at high code rates and the built-in synchronization algorithm allows
the Viterbi decoder to lock onto signals with very poor signal-to-noise ratios. A Viterbi bit error rate monitor provides
an indication of the error rate at the QPSK output.
The 24-bit error count register in the Viterbi decoder allows the bit error rate at the output of the QPSK demodulator
to be monitored. The 24-bit bit error count register in the Reed-Solomon decoder allows the Viterbi output bit error
rate to be monitored. The 16-bit uncorrectable packet counter yields information about the output packet error rate.
These three monitors and the QPSK SNR register allow the performance of the device and its individual
components, such as the QPSK demodulator and the Viterbi decoder, to be monitored extensively by the external
microprocessor. The frame/byte align block features a sophisticated synchronization algorithm to ensure reliable
recovery of DVB and DSS framed data streams under worst case signal conditions. The de-interleaver uses on-
chip RAM and is compatible with the DVB and DSS algorithms. The Reed-Solomon decoder is a truncated version
of the (255, 239) code. The code block size is 204 for DVB and 146 for DSS. The decoder provides a count of the
number of uncorrectable blocks as well as the number of bit errors corrected. The latter gives an indication of the bit
error rate at the output of the Viterbi decoder. In DVB mode, spectrum de-scrambling is performed compatible with
the DVB specification. The final output is a parallel or serial transport data stream, packet sync, data clock and a
block error signal. The data clock may be inverted under software control.
2.4.1 Viterbi Error Count Measurement
A method of estimating the bit error rate at the output of the QPSK block has been provided in the Viterbi decoder.
The incoming data bit stream is delayed and compared with the re-encoded and punctured version of the decoded
bit stream to obtain a count of errors, see Figure 5. The measurement system has a programmable register to
determine the number of data bits (the error count period) over which the count is being recorded. A read register
indicates the error count result and an interrupt can be generated to inform the host microprocessor that a new
count is available.
The VIT_ERRPER_register is programmed with the required number of data bits (the error count period)
(VIT_ERRPER[7:0]). The count of errors found during this period is loaded by the CE6313 into the
VIT_ERRCNT_H-M-L trio of registers when the bit count VIT_ERRPER[7:0] is reached. At the same time an
interrupt is generated on the IRQ line. Setting the IE_FEC[2] bit in the IE_FEC register enables the interrupt.
Reading the register does not clear VIT_ERRCNT [23:0], it is only loaded with the error count.

Figure 6 shows the bit errors rising until the maximum programmed value of VIT_ERRPER is reached, when an
interrupt is generated on the IRQ line to advise the host microprocessor that a new value of bit error count has been
loaded into the VIT_ERRCNT [23:0] register. The IRQ line will go high when the IE_FEC register is read by the host

2.4.1.1 Viterbi Error Count Coarse Indication
To assist in the process of aligning the receiver dish aerial, a coarse indication of the number of bit errors being
received can be provided by monitoring the STATUS line with the following set up conditions.
The frequency of the output waveform will be a function of the bit error count (triggering the maximum value
programmed into the VIT_MAXERR[7:0] register and the dish alignment on the satellite. This VIT_MAXERR mode
is enabled by setting the FEC_STAT_EN register bit-0. Figure 7 shows the bit errors rising to the maximum value
programmed and triggering a change of state on the STATUS line.

2.4.2 The Frame Alignment Block
The frame alignment algorithm detects a sequence of correctly spaced synchronizing bytes in the Viterbi decoded
bit-stream and arranges the input into blocks of data bytes. Each block consists of 204 bytes for DVB and 147 bytes
for DSS. In the DSS mode, the synchronizing byte is removed from the data stream, so only 146 bytes of a block
are passed to the next stage. The frame alignment block also removes the 180° phase ambiguity not removed by
the Viterbi decoder.
2.4.3 The De-Interleaver Block
2.4.3.1 DVB
Before transmission, the data bytes are interleaved with each other in a cyclic pattern of twelve. This ensures the
bytes are spaced out to avoid the possibility of a noise spike corrupting a group of consecutive message bytes.
Figure 8 below shows conceptually how the convolutional de-interleaving system works. The synchronization byte
is always loaded into the First-In-First-Out (FIFO) memory in branch 0. The switch is operated at regular byte
intervals to insert successively received bytes into successive branches. After 12 bytes have been received,
byte 13 is written next to the synchronization byte in branch 0, etc. In the CE6313, this de-interleaving function is
realized using on-chip Random Access Memory (RAM).

2.4.4 The Reed-Solomon Decoder Block
DVB and DSS data are encoded using shortened versions of the Reed-Solomon code of block length 255,
containing 239 message bytes and 16 check bytes, that is (255,239) with T = 8. Both encoders use the same
generator polynomial. The code block size for DVB is 204 and that for DSS is 146. Hence DVB code is (204, 188)
and DSS code is (146, 130), with both having T = 8. The block structure of the DVB and DSS Reed-Solomon codes
are as shown in Figure 10 and Figure 11 below.
The Reed-Solomon decoder can correct up to eight byte errors per packet. If there are more than eight bytes
containing errors, the packet is flagged as uncorrectable using the BKERR pin 63. In the case of DVB the Transport
Error Indicator (TEI) bit of the MPEG packet is set to 1, if setting of TEI is enabled.

2.4.5 The Energy Dispersal (de-scrambler) Block, DVB Only
Before Reed-Solomon encoding in the DVB transmission system, the MPEG2 data stream is randomised using the
configuration shown in Figure 12 below. This is a Pseudo Random Binary Sequence (PRBS) generator, with the
polynomial:
14
15
1 + X + X
The PRBS registers are loaded with the initialisation sequence as shown, at the start of the first transport packet in
a group of eight packets. This point is indicated by the inverted sync byte 0xB8 (the normal DVB sync byte is 0x47).
The data starting with the first byte after the sync byte are randomised by exclusive-ORing data bits with the PRBS
(the sync bytes themselves are not randomised). In the decoder, the process of de-randomising or de-scrambling
the data is exactly the same as described above. The de-scrambler also inverts the sync byte 0xB8 so that all
MPEG output packets have the same sync byte 0x47.

2.4.6 Output Stage
The transport stream can be output in a byte-parallel or bit-serial mode. The output interface consists of an 8-bit
output, output clock, a packet validation level, a packet start pulse and a block error indicator.
The output clock rate depends on the symbol rate, QPSK/BPSK choice, convolutional (Viterbi) coding rate,
DVB/DSS choice and byte-parallel or bit-serial output mode. This rate is computed by CE6313 to be very close to
the minimum required to output packet data without packet overlap. Furthermore, the packets at the output of
CE6313 are as evenly spaced as possible to minimize packet position movement in the transport layer. The
maximum movement in the packet synchronization byte position is limited to ±1 output clock period.
2.5 Control
Automatic symbol rate search, code rate search, signal acquisition and signal tracking algorithms are built into the
CE6313 using a sophisticated on-chip controller. The software interaction with the device is via a simple Command
Driven Control (CDC) interface. This CDC maps high level inputs such as symbol rates in MSps and frequencies in
MHz, to low level on-chip register settings. The on-chip control state machine and the CDC significantly reduces the
software overhead as well as the channel search times. There is also an option for the host processor to by-pass
both the CDC as well as the on-chip controller and take direct control of the QPSK demodulator. Once the CE6313
has locked to the signal, any frequency offset can be read from the LNB_FREQ error registers 7 and 8. The
frequency synthesiser under the software control can be re-tuned in frequency to optimise the received signal
within the baseband filter bandwidth. Note that CE6313 compensates for any frequency offsets before QPSK
14
Intel Corporation
CE6313
Data Sheet
demodulation. Hence a frequency offset will not necessarily lead to a performance loss. Performance loss will occur
only if a significant part of the signal is cut off by the base-band filter, due to this frequency offset. This will happen
only if the symbol rate is close to the maximum supported by that filter. In such an event it is recommended that
front-end be re-tuned to neutralise this error before the filter. It is then necessary for the CE6313 to re-acquire the
signal.
The CE6313 can generate control signals to enable full control of the dish and LNB. The chip implements the
signals needed for the full DiSEqC specification. This includes high/low band selection, polarization and dish
position. In this mode, the symbol rate in MSps and Viterbi code rate are the only values needed to start the
CE6313 searching for the signal. The CDC module maps the high level parameters into the various low level
register settings needed to acquire and track the signal. The low level registers may be read and directly modified
to suit very specific requirements. However, this is not recommended.

2.5.1 Symbol Rate and Code Rate Search Mode
Where the symbol rate and/or the Viterbi code rate are unknown, the CE6313 can be programmed to search for
QPSK/BPSK signals. The user should define the range(s) over which the search is required. The CE6313 will then
locate and track any signal detected. Failure to find a QPSK signal in the specified frequency and specified symbol
rate ranges will be indicated by interrupts. CE6313 will carry on searching these ranges after issuing these
interrupts. When the CE6313 has locked onto a signal, the symbol rate in MSps may be read from the MONITOR
registers. The Viterbi code rate may be read from the FEC_STATUS register. This search facility is primarily for use
during the initial installation of a receiver.
2.6 DiSEqC Transmit and Receive Messages
The CE6313 has the capability to send and receive DiSEqC messages. Eight registers are provided to store a
message for transmission and a further eight registers are provided to store a received message. The received
bytes have a parity bit and a parity error bit in addition to the eight data bits. These additional bits are read out in
sequence following the data bits, so two byte reads are required for each data byte.
2.6.1 DiSEqC Transmitting Messages
The sequence of events to send a message are as follows:
1. Load the required message bytes into the DiSEqC instruction register. Sequential writes to the same register are
achieved by setting the Inhibit Auto Incrementing (IAI) bit 7 in RADD, the register address byte.
2. Load the number of bytes (less one) in the DiSEqC instruction in the register DiS_Mode[5:3].
15
Intel Corporation
CE6313
Data Sheet
3. Set DiS_Mode[2:0] = 4 to command the CE6313 to encode the data and transmit the message.
4. Reset DiS_Mode[2:0] to either 0 or 1 depending on previous setting of 22 kHz off or on. The data loaded into the
DiSEqC_INSTR register is retained, so that if the same message is to be repeated, stage 1 above can be omit-
ted.
2.6.2 DiSEqC Receiving Messages
The CE6313 will automatically listen for DiSEqC messages 5 ms after a message has been transmitted. If a return
message is expected, the DiS_Mode[2:0] must be set to zero in order to leave the LNB control signal free for
another DiSEqC transmitter to respond. The sequence of events to receive a message are as follows:
1. Ensure that DiSEqC2/GPP2 pin 2 is an input by setting GPP_CTRL register address-20 bit-5 to zero.
2. Enable interrupts if the IRQ pin 43 is used to interrupt the host processor in DiSEqC2_CTRL1 register 121.
3. Monitor DiS_INT register.
4. If bit-3 = 1 and bit-1 = 0, there has been no message received.
5. If a message has been received, bit-0 will be set. If bit-1 is also set the message is complete. DiS_INT register
bits-7-4 indicate how many bytes have been received.
6. Read the received message from DiS_FIFO register 120 by setting the Inhibit Auto Incrementing (IAI) bit-7 in
RADD, the register address byte and sequentially reading DiS_FIFO for the indicated number of bytes. Each
data byte read requires two 2-wire bus reads. The second or the pair of bytes contains the parity bit and a parity
bit error indicator.
The user may choose to wait for the end of message indication, before reading the message, if it is known that the
message is not greater than eight bytes. However, if the length of message is not known, the message should be
read out of the FIFO by the host as it is being received. Care must be taken to avoid a FIFO buffer overflow.
DiS_INT register bits-7-4 will indicate how many bytes remain in the FIFO.
3.0 Microprocessor Control
3.1 RADD: 2-wire Register Address (W)
RADD is the internal 2-wire bus register address. It is the first byte written after the CE6313 2-wire bus address
when in write mode.
To write to the chip, the bus master should send a START condition and the chip address with the write bit set,
followed by the register address where subsequent data bytes are to be written. Finally, when the 'message' has
been sent, a STOP condition is sent to free the bus.
To read from the chip from register address zero, the bus master should send a START condition and the chip
address with the read bit set, followed by the requisite number of clocks to read the bytes out. Finally a STOP
condition is sent to free the bus. RADD is not sent in this case.
To read from the chip from an address other than zero, the bus master should send the chip address with the write
bit set, followed by the register address from where subsequent data bytes are to be read. Then the bus master
should send a repeat START condition and the chip address with the read bit set, followed by the requisite number
of CLK1 clocks to read the required bytes out. Finally a STOP condition is sent to free the bus. A STOP condition
resets the RADD value to 00.

register address, numbers in the range 0 to 127 are allowed
When the register address is incremented to 127 it stops and the bus will continue to write to or read from register
127 until a STOP condition is sent.
3.2 Primary 2-wire Bus Interface
The primary 2-wire bus serial interface uses pins:
DATA1 (pin 11) serial data, the most significant bit is sent first.
CLK1 (pin 10) serial clock.
The 2-wire bus address is determined by applying Vdd or Gnd to the ADDR[4:1] pins while the three MSBs of the
address are internally set to ‘0’.
For compatibility with earlier devices, the 2-wire bus address will normally be 0001 110 R/W and the pins connected
as follows:
Addr[4] Addr[3] Addr[2] Addr[1]
Vdd
Vdd
Vdd
Gnd
When the CE6313 is powered up, the Reset pin 1 should be maintained low for typically 100 ms after Vdd and
CVdd have reached normal operation levels, and the Sleep pin 9 has gone low. This is to ensure that the crystal
oscillator and internal PLL have become fully established and that the internal reset signal is fully clocked into all
parts of the circuit. As the reset pin is pulled high, the logic levels on Addr[4:1] are latched to become the 2-wire bus
address AD[6:0].
The circuit works as a slave transmitter with the eighth bit set high or as a slave receiver with the eighth bit set low.
In receive mode, the first data byte is written to the RADD virtual register, which forms the register sub-address.
Bit 7 of the RADD register, IAI is an Inhibit Auto Increment function. When the IAI bit is set high, the automatic
incrementing of register addresses is inhibited. IAI set low is the normal situation so that data bytes sent on the
2-wire bus after the RADD register data are loaded into successive registers. This automatic incrementing feature
avoids the need to individually address each register.
Following a valid chip address, the 2-wire bus STOP command resets the RADD register to 00. If the chip address
is not recognised, the CE6313 will ignore all activity until a valid chip address is received. The 2-wire bus START
command does NOT reset the RADD register to 00. This allows a combined 2-wire bus message to point to a
particular read register with a write command, followed immediately with a read data command. If required, this
could next be followed with a write command to continue from the latest address. Finally a STOP command should
be sent to free the bus.
When the 2-wire bus is addressed (after a recognised STOP command) with the read bit set, the first byte read out
will be the content of register 00.

3.3 Secondary 2-wire Bus for Tuner Control
The CE6313 has a General Purpose Port that can be configured to provide a secondary 2-wire bus with full bi-
directional operation. When pass-through is enabled, a transparent connection is made to the tuner. This innovative
design simplifies the software required to program the tuner.
Pass-through mode is selected by setting register (20) GPP_CTRL[bit-6] = 1.
The allocation of the pins is: DATA2 = pin14, CLK2 = pin 15.
