3339-00

3.0 GHz Integer-N PLL for Low Phase Noise Applications

Peregrine Semiconductor 

Product Description

Peregrine’s PE3339 is a high performance integer-N PLL

capable of frequency synthesis up to 3.0 GHz. The

superior phase noise performance of the PE3339 makes

it ideal for applications such as wireless local loop

basestations, LMDS systems and other demanding

terrestrial systems.

The PE3339 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.

Fabricated in Peregrine’s patented UTSi® (Ultra Thin

Silicon) CMOS technology, the PE3339 offers excellent

RF performance with the economy and integration of

conventional CMOS.
