4x4 mm 20-lead QFN

The PE42742 is an SPDT UltraCMOS™ Switch designed for

Broadband applications such as CATV, DTV, Multi-Tuner

DVR (Digital Video Recorder), Set-top Box, PCTV and Game

Boxes. It meets FCC 15.115 spec of 80 dB isolation @ 216

MHz and offers high isolation and low insertion loss in both a

powered and a unique unpowered default state. The

PE42742 covers a broad frequency range from 5 MHz to

beyond 2200 MHz with a single positive supply and CMOS

control. It provides a smaller, cost effective, more reliable

and manufacturable alternative to mechanical relays in set-

top box applications.

The PE42742 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

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

rating specified.

Latch-Up Avoidance

Unlike conventional CMOS devices, UltraCMOS™

devices are immune to latch-up.

Table 5. Operating Conditions @ 25 °C

Notes: 1. RF pins 3, 8, and 13 must be at 0 VDC. The RF pins do

not require DC blocking capacitors for proper operation if the

0 V DC requirement is met.

2. Pins 16 and 17 can be set for single pin or complementary

pin control.

Switching Frequency

The PE42742 has a maximum 25 kHz switching rate.

Exceeding absolute maximum ratings may cause

Typical Applications

The PE42742 provides the high isolation required

by FCC part 15.115 regulation between the

television antenna and the cable plant. The

advantage of the PE42742 is that device

isolation / thru performance is maintained when

power is removed. This unique feature makes the

PE42742 ideal for set-top box and VCR

applications. The PE42742 supports signal flow

from RFC to RF1 and RF2 termination in the

unpowered state; similar to the powered state with

C1=C2 (both high or low).

Evaluation Kit

The SPDT Switch Evaluation Kit facilitates

customer evaluation of the PE42742 SPDT

switch. The RF common port is connected

through a 75 Ω transmission line to J2. Ports 1

and 2 are connected through 75 Ω transmission

lines to J1 and J3. A through line connects F

connectors J4 and J5. This transmission line can

be used to estimate the PCB loss over the

environmental conditions. J6 provides DC and

digital inputs to the device.

The board is composed of a two metal layer FR4

material with a total thickness of 0.032”. The

transmission lines are hybrid microstrip/coplanar

waveguide with ground plane (28 mil core, 12 mil

width, 12 mil gap).

The provided jumpers short the control pins to

ground for logic low. With the jumper removed the

control input rises to VDD for logic high through the

1 MΩ pull up resistor. These resistors will draw

several microamps from VDD. They are not

required for normal operation.
