The PE 43 503 is a HaR P™-enhanced, high linearity, 5-bit RF

Digital Step Attenuator (DSA) covering a 31 dB attenuation

range in 1 dB steps. The Peregrine 50Ω RF DS A pr ov ides a

serial CMOS control interface. It ma intains 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.

The PE43503 is manufactured on Peregrine’s UltraCMOS™

pro c ess, a patented variation of silicon -on-insulator (SOI)

technology on a sapphire substrate, offering the performance

of GaAs with the eco nom y an d i nte gr ation of co nventi on al

CMOS.

sensit ive devices . Alt hough this devic e contains

circ uitry to protect it from dam age due to ES D,

Switc hing rate is defined to be the speed at which the

DSA can be toggled across attenuation st ates.

Exceeding absolute m ax im um r atings may cause

permanent damage. Operation should be res tricted to

the limits in t he Operating Ranges t able. Operat ion

Programming Options

Parallel/Serial Selection

Either a parallel or serial interface can be used to

control the PE43503. 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 five 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. 16 (Parallel Interface Timing

Diagram), Table 11 (Pa rallel 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

at tenuation state control v alues will change devic e

state to new attenuation. Direct Mode is ideal for

manual control of the device (using hardwire,

switches, or jumpers).

Seri al Int er face

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 d i agram for

programming a state. When the DSA is used in

serial mode, ground all parallel control pins (pins 19-

23).

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.

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 reg i s ter is illustrated in Table 9. The serial

timin g dia gram is illustrated in Fig. 15. It is required

that all parallel pins be grounded when the DSA is

used in serial mode.

Power-up Control Settings

The PE43 503 will always init ialize t o the maximum

attenuation setting (31 dB) on power-up for both the

serial and latched-parallel modes of operation and

will remain in this s etting until the user latches in the

next programming word. In direct-parallel mode, the

DSA can be preset to any state within the 31 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 dB) before defaulting to the user defined

state. If the control pins are left floating in this mode

during power-up, th e device will default to t he

minimum attenuation setting (insertion loss state).

Dynamic operation between serial and parallel

programming modes is possible.

If the DSA powers up in serial mode (P/S = HIGH),

all the parallel control inputs DI[6:2] must be set to

logic low. Prior to toggling to parallel mode, the DSA

must be programmed serially to ensure D[7] is set to

logic low.

If the DSA powers up in either latched or direct-

parallel mode, all parallel pins DI[6:2] must be set to

logic low prior to toggling to serial 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 and parallel programming modes at

will.

Evaluation Kit

The Di gi tal Att en ua t or E val u ation Kit bo ar d w as

designed to ease cus t om er eval u ation of th e

PE43503 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

Pa rallel/S erial (P/ S) select switch to the Para llel

(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 mod e.

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 rallel/S erial (P/ S) select switch to the Para llel

(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

paralle l input. When toggled ‘DOWN’, logic low is

presented to the parallel input. Setting D0-D6 to

the ‘MID DL E’ toggle pos iti on pr esents an OPEN,

which forces an on-chip logic low. Table 9 depicts

the parallel programming truth table and Fig. 16

illust rate s the pa ralle l programming timing

diagram.

Latc he d- P ar al l el Program m i ng Pr oc edure

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

Figure 17. Evaluati on Board Layout

Peregr ine S pec ificat ion 101- 0310

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.

Seri al Pr ogramm i ng Pr ocedur e

Po sition 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.
