The PE 43 701 is a HaRP-enhanced, high linearity, 7-bit RF
Digital Step Attenuator (DSA). This highly versatile DSA
covers a 31.75 dB attenuation ra nge in 0.25 dB steps. The
Peregri ne 50 RF D SA pr ov ides a parall el or s eri al -
addressable CMOS control interface. It maintains high
att en uation acc ur acy over frequ enc y and tem p er ature an d
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
5x5 mm 32-lead QFN footprint.
The PE43701 is manufactured on Peregrine’s UltraCMOS™
pro cess, a patented variation of silicon-o n-insulator (SOI)
technology on a sapphire substrate, offering the performance
of GaAs with the econom y an d i nte gr ation of conventi on al
CMOS.

Programming Options
Par all el/ Serial-Ad dressable Sele ct ion
Either a parallel or serial-addressable interface can
be used to control the PE43701. The P/S b it
provides this selectio n, with P/S=LOW selecting the
parallel interface and P/S=HIGH selecting the serial
interface.
Parallel Mode Interface
The parallel interface consists of seven CMOS-
compatible control lines that select the desired
attenuation state, as shown in T abl e 7.
The parallel interface timing requirements are
defined by Fig. 21 (Parallel Interface Timing
Diagram), Table 12 (Pa rallel In terface 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. 21) to latch new attenuation state into
device.
For direct parallel programming, the Latch Enable
(LE) line should be pulled HIGH. Changing
at tenuation stat e contro l v alues will c hange device
state to new attenuation. Direct Mode is ideal for
manual control of the device (using hardwire,
switches, or jumpers).
Serial-Addressable Interface
The serial-addressable interface is a 16-bit serial-in,
parallel-out shift register buffered by a transparent
latch. The 16-bits make up two words comprised of
8-bits each. The first word is the Attenuation Word,
which controls the state of the DSA. The second
word is the Address Word, which is compared to the
static (or programmed) logical states of the A0, A1
and A2 digital inputs. If there is an address match,
the DSA changes state; otherwise its current state
will rema in un ch anged. Fig. 20 illustrates a example
timing diagram for programming a state. It is
recommended that all parallel control inputs be
grounded when the DSA is used in Serial Mode.
The serial-addressable 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,
beginning with the Attenuation Word.
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. Address word and
attenuation word truth tables are listed in Table 8 &
Table 9, respectively. A programming example of the
serial-addressable register is illustrated in T abl e 10.
The serial-addressable timing diagram is illustrated
in Fig. 20.
Power-up Control Setti ngs
The PE43701 will a lways initialize to the maximum
attenuation setting (31.75 dB) on power-up for both
the serial-addressable and latched-parallel modes of
operation and will remain in this sett ing until t he us er
latches in the next programming word. In direct-
parallel mode, the DSA can be preset to any state
within the 31.75 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
(31.75 dB) before defaulting to the user defined
state. If the control pins are left floating in this mode
during power-up, the devic e will default to the
minimum attenuation setting (insertion loss state).
Dynamic operation between serial-addressable and
parallel programming modes is possible.
If the DSA powers up in serial-addressable mode (P/
S = HIGH), all the parallel control inputs DI[6:0] must
be set to logic low. Prior to toggling to parallel mode,
the DSA must be programmed serially to ensure
D[7 ] is set t o logic low.
If the DSA powers up in either latched or direct-
parallel mode, all parallel pins DI[6:0] must be set to
logic low prior to toggling to serial-addressable mode
(P/S = HIGH), and held low until the DSA has been
programmed serially to ensure bit D[7] is set to logic
low.
The sequencing is only required once on power-
up. Once completed, the DSA may be toggled
between serial-addressable and parallel
programming modes at will.

The Di gi tal Att en ua t or E val u ation Kit bo ard w as
designed to eas e c ustomer ev aluation of the
PE43701 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
‘MIDDL E’ toggle po s ition. Position the Para llel/
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 Mo de. 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
Pa ralle l/Serial (P/S) select switch to the Para llel (or
left) positi o n. Th e LE pin on the Ser ial he ad er mu st
be tied to VDD. Switches D0-D6 are SP3T switches
whi ch en abl e t he user to m an ual l y pr ogram 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 F i g. 21 illustrates the
parallel programming timing diagram.
Latc he d- P ar al l el Pr ogramm i ng Pr ocedur e
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
as the parallel bits are applied. The user must then
pulse LE from 0V to V DD and back to 0V to latch the
programming word into the DSA. LE must be logic
low prior to pr ogrammi ng th e nex t wor d .

Seri al - A ddr es s able Programm i ng Pr oc edure
Po sition the Parallel/Serial (P/S) select switch to
the Serial (or right) position. Prior to
programming, the user must define an address
setting using the ADD header pin. Jump the
mi ddl e pins o n the AD D hea der A0-A2 (or lower )
row of pins to set logic high, or jump the middle
pins to the upper row of pins to set logic low. If
the ADD pi ns are l eft op e n, the n 000 become the
default address. The evaluation so ftware is
written to operate the DSA in either Parallel or
Serial-Addressable Mode. Ensure that the
software is set to program in Serial-Addressable
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.
