Product Specification

PE3342

2.7 GHz Integer-N PLL

with Field-Programmable EEPROM

Product Description

Features

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.

• Field-programmable EEPROM for self-

starting applications

• Standard 2700 MHz operation,

3000 MHz speed-grade option

• ÷10/11 dual modulus prescaler

• Internal phase detector

• Serial programmable

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.

• Low power — 20 mA at 3 V

• Ultra-low phase noise

• Available in 24-lead TSSOP or 20-lead

4x4 mm QFN package

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.
