The PE42750 is an SPDT UltraCMOS® Switch designed

for Broadband applications such as CATV, DTV, Multi-

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

and Video Game Consoles. The PE42750 meets FCC

15.115 specification of 80 dB isolation at 216 MHz in

both powered and unpowered states. The PE42750

covers a broad frequency range from 5 MHz to 2200

MHz with a single positive supply and CMOS control.

The PE42750 provides a smaller, cost effective, more

reliable and manufacturable alternative to mechanical

relays in set-top box applications.

The PE42750 is manufactured using 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.

Table 4. Operating Conditions @ 25°C

Notes: 1. RF pins 2, 5, and 8 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 10 and 11 can be set for single pin control

3. GND must be connected to exposed ground paddle to ensure

good isolation

Exceeding absolute maximum ratings may cause permanent

damage. Operation between operating range maximum and

absolute maximum for extended periods may reduce reliability.

Moisture Sensitivity Level

The Moisture Sensitivity Level rating for the PE42750 in

the 12-lead 3 x 3 x 0.75 mm QFN package is MSL1.

Switching Frequency

The PE42750 has a maximum 25 kHz switching rate.

Latch-Up Avoidance

Unlike conventional CMOS devices, UltraCMOS®

devices are immune to latch-up.

Operation should be restricted to the limits in the Operating

Ranges table.

Typical Applications

The PE42750 provides the high isolation required by

FCC part 15.115 regulation between the television

antenna and the cable plant. The advantage of the

PE42750 is that device isolation performance is

maintained when power is removed. When the PE42750

is unpowered all ports are terminated.

The SPDT Switch Evaluation Kit facilitates

customer evaluation of the PE42750 SPDT switch.

The RF common port is connected through a 75 

transmission line to J2. Ports 1 and 2 are

connected through 75  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.
