Product Specification

PE3239

2.2 GHz UltraCMOS™ Integer-N PLL

for Low Phase Noise Applications

Product Description

Features

Peregrine’s PE3239 is a high performance integer-N PLL

capable of frequency synthesis up to 2.2 GHz. The

superior phase noise performance of the PE3239 is ideal

for applications such as wireless local loop basestations,

LMDS systems and other demanding terrestrial systems.

• 2.2 GHz operation

• ÷10/11 dual modulus prescaler

• Internal phase detector with

charge pump

The PE3239 features a 10/11 dual modulus prescaler,

counters, phase detector and a charge pump as shown in

Figure 1. Counter values are programmable through a

three wire serial interface.

• Serial programmable

• Low power— 20 mA at 3 V

• Ultra-low phase noise

The PE3239 is manufactured on 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.

• Available in 20-lead TSSOP
