PE43602
50 Ω RF Digital Attenuator
6-bit, 31.5 dB, DC-5.0 GHz
Product Description
Features
The PE43602 is a HaRP™-enhanced, high linearity, 6-bit RF
Digital Step Attenuator (DSA) covering a 31.5 dB attenuation
range in 0.5 dB steps. This Peregrine 50Ω RF DSA provides
both a serial and parallel CMOS control interface. It maintains
high attenuation accuracy over frequency and temperature and
exhibits very low insertion loss and low power consumption.
Performance does not change with Vdd due to on-board
regulator. This next generation Peregrine DSA is available in a
4x4 mm 24 lead QFN footprint.
• HaRP™-enhanced UltraCMOS™ device

• High Linearity: Typical +58 dBm IP3
• Excellent low-frequency performance
• 3.3 V or 5.0 V Power Supply Voltage

• Programming Modes:
The PE43602 is manufactured on Peregrine’s UltraCMOS™
process, a patented variation of silicon-on-insulator (SOI)
technology on a sapphire substrate, offering the performance
of GaAs with the economy and integration of conventional
CMOS.

Electrostatic Discharge (ESD) Precautions
The PE43602 has a maximum 25 kHz switching rate.
Switching rate is defined to be the speed at which the
DSA can be toggled across attenuation states.
When handling this UltraCMOS™ device, observe the
same precautions that you would use with other ESD-
sensitive devices. Although this device contains
circuitry to protect it from damage due to ESD,
precautions should be taken to avoid exceeding the
specified rating.
Latch-Up Avoidance
Unlike conventional CMOS devices, UltraCMOS™
devices are immune to latch-up.

Attenuation Word
Attenuation Word is derived directly from the attenuation value. For example, to program the 12.5 dB state:
Attenuation Word: Multiply by 4 and convert to binary → 4 * 12.5 dB → 50 → X0110010
Serial Input: X0110010

PE43602
Product Specification
Programming Options
The shift register must be loaded while LE is held
LOW to prevent the attenuator value from changing
as data is entered. The LE input should then be
toggled HIGH and brought LOW again, latching the
new data into the DSA. Attenuation Word truth table
is listed in Table 8. A programming example of the
serial register is illustrated in Table 9. The serial
timing diagram is illustrated in Fig. 15.
Parallel/Serial Selection
Either a parallel or serial interface can be used to
control the PE43602. The P/S bit provides this
selection, with P/S=LOW selecting the parallel
interface and P/S=HIGH selecting the serial
interface.
Parallel Mode Interface
The parallel interface consists of six CMOS-
compatible control lines that select the desired
attenuation state, as shown in Table 7.
Power-up Control Settings
The PE43602 will always initialize to the maximum
attenuation setting (31.5-dB) on power-up for both
the serial and latched-parallel modes of operation
and will remain in this setting until the user latches
in the next programming word. In direct-parallel
mode, the DSA can be preset to any state within
the 31.5-dB range by pre-setting the parallel
control pins prior to power-up. In this mode, there
is a 400-µs delay between the time the DSA is
powered-up to the time the desired state is
set. During this power-up delay, the device
attenuates to the maximum attenuation setting
(31.5-dB) before defaulting to the user defined
state. If the control pins are left floating in this
mode during power-up, the device will default to
the minimum attenuation setting (insertion loss
state).
The parallel interface timing requirements are
defined by Fig. 16 (Parallel Interface Timing
Diagram), Table 11 (Parallel Interface AC
Characteristics), and switching speed (Table 1).
For latched-parallel programming the Latch
Enable (LE) should be held LOW while changing
attenuation state control values, then pulse LE
HIGH to LOW (per Fig. 16) to latch new
attenuation state into device.
For direct parallel programming, the Latch Enable
(LE) line should be pulled HIGH. Changing
attenuation state control values will change device
state to new attenuation. Direct Mode is ideal for
manual control of the device (using hardwire,
switches, or jumpers).
Serial Interface
The serial interface is a 8-bit serial-in, parallel-out
shift register buffered by a transparent latch. The
8-bits make up the Attenuation Word that controls
the DSA. Fig. 15 illustrates a example timing
diagram for programming a state.
The serial-interface is controlled using three
CMOS-compatible signals: Serial-In (SI), Clock
(CLK), and Latch Enable (LE). The SI and CLK
inputs allow data to be serially entered into the
shift register. Serial data is clocked in LSB first.

Product Specification
Figure 17. Evaluation Board Layout
Peregrine Specification 101-0310
Evaluation Kit
The Digital Attenuator Evaluation Kit board was
designed to ease customer evaluation of the
PE43602 Digital Step Attenuator.
Direct-Parallel Programming Procedure
For automated direct-parallel programming,
connect the test harness provided with the EVK
from the parallel port of the PC to the J1 & Serial
header pin and set the D0-D6 SP3T switches to
the ‘MIDDLE’ toggle position. Position the
Parallel/Serial (P/S) select switch to the Parallel
(or left) position. The evaluation software is
written to operate the DSA in either Parallel or
Serial-Addressable Mode. Ensure that the
software is set to program in Direct-Parallel mode.
Using the software, enable or disable each setting
to the desired attenuation state. The software
automatically programs the DSA each time an
attenuation state is enabled or disabled.
For manual direct-parallel programming,
disconnect the test harness provided with the EVK
from the J1 and Serial header pins. Position the
Parallel/Serial (P/S) select switch to the Parallel
(or left) position. The LE pin on the Serial header
must be tied to VDD. Switches D0-D6 are SP3T
switches which enable the user to manually
program the parallel bits. When any input D0-D6
is toggled ‘UP’, logic high is presented to the
parallel input. When toggled ‘DOWN’, logic low is
presented to the parallel input. Setting D0-D6 to
the ‘MIDDLE’ toggle position presents an OPEN,
which forces an on-chip logic low. Table 9 depicts
the parallel programming truth table and Fig. 16
illustrates the parallel programming timing
diagram.
Note: Reference Figure 18 for Evaluation Board Schematic
as the parallel bits are applied. The user must
then pulse LE from 0V to VDD and back to 0V to
latch the programming word into the DSA. LE
must be logic low prior to programming the next
word.
Serial Programming Procedure
Position the Parallel/Serial (P/S) select switch to
the Serial (or right) position. The evaluation
software is written to operate the DSA in either
Parallel or Serial Mode. Ensure that the software
is set to program in Serial mode. Using the
software, enable or disable each setting to the
desired attenuation state. The software
automatically programs the DSA each time an
attenuation state is enabled or disabled.
Latched-Parallel Programming Procedure
For automated latched-parallel programming, the
procedure is identical to the direct-parallel
method. The user only must ensure that Latched-
Parallel is selected in the software.
For manual latched-parallel programming, the
procedure is identical to direct-parallel except now
the LE pin on the Serial header must be logic low
