PSEMI PE42742

Product Specification
PE42742
75 Ω Terminated, 5 - 2200 MHz SPDT
CATV UltraCMOS™ Switch
Featuring Unpowered Operation
Product Description
The PE42742 is an SPDT UltraCMOS™ switch designed
for broadband applications such as CATV, DTV, MultiTuner 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.
Features
The PE42742 is manufactured on Peregrine’s
UltraCMOS™ process, a patented variation of silicon-oninsulator (SOI) technology on a sapphire substrate,
offering the performance of GaAs with the economy and
integration of conventional CMOS.

Exceeding absolute maximum ratings may cause
permanent damage. Operation should be restricted to
the limits in the Operating Ranges table. Operation
between operating range maximum and absolute
maximum for extended periods may reduce reliability.
Electrostatic Discharge (ESD) Precautions
When handling this UltraCMOS™ device, observe the
same precautions that you would use with other ESDsensitive 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.
Switching Frequency
The PE42742 has a maximum 25 kHz switching rate.

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).
Note: A versatile logic table has been established to allow either C1 or C2 act
as a single pin control and in either polarity.

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.
Figure 18. Evaluation Board Layouts
Peregrine Specification 101/0269
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.
