PE4248
Product Description
The PE4248 is a high-isolation MOSFET Switch
designed for CATV applications, covering a broad
frequency range from DC up to 1.3 GHz. This single-
supply SPST switch offers a single-pin CMOS control
interface with industry leading CTB performance. It also
provides low insertion loss, high isolation and extremely
low bias requirements while operating on a single 3-volt
supply. In a typical CATV application, the PE4248
provides for a cost effective and manufacturable solution
vs. mechanical relays.
The PE4248 is manufactured in Peregrine’s patented
Ultra Thin Silicon (UTSi) CMOS process, offering the
performance of GaAs with the economy and integration
of conventional CMOS.

Product Specification
Electrostatic Discharge (ESD) Precautions
When handling this UTSi 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, UTSi CMOS
devices are immune to latch-up.
Device Description
The PE4248 high isolation SPST CATV Switch is
designed to support CATV applications such as
premise disconnect of a CATV signal path. This
function is typically performed by bulky and
expensive mechanical relays. The high isolation
characteristics, high compression point, and
integrated 75-ohm terminations make the PE4248
an ideal, cost effective and manufacturable product
of choice.

Notes: 1. CTRL accepts both CMOS and TTL voltage leads.
The control logic input pin (CTRL) is typically driven
by a 3-volt CMOS logic level signal, and has a
threshold of 50% of VDD. For flexibility to support
systems that have 5-volt control logic drivers, the
control logic input has been designed to handle a 5-
volt logic HIGH signal. (A minimal current will be
sourced out of the VDD pin when the control logic
input voltage level exceeds VDD.)
