Product Specification

PE3342

Product Description

Peregrine’s PE3342 is a high performance integer-N PLL with

embedded EEPROM capable of frequency synthesis up to

2700 MHz with a speed-grade option to 3000 MHz. The

EEPROM allows designers to permanently store control bits,

allowing easy configuration of self-starting synthesizers. The

superior phase noise performance of the PE3342 is ideal for

applications such as wireless base stations, fixed wireless, and

RF instrumentation systems.

The PE3342 features a ÷10/11 dual modulus prescaler,

counters, and a phase comparator as shown in Figure 1.

Counter values are programmable through a three-wire serial

interface.

The PE3342 UltraCMOS™ Phase Locked-Loop is

manufactured in Peregrine’s patented Ultra Thin Silicon

(UTSi®) CMOS process, offering excellent RF performance

with the economy and integration of conventional CMOS.
