3340-00

3.0 GHz Integer-N PLL for Low Phase Noise Applications

Peregrine Semiconductor Corp. 

Product Description

Peregrine’s PE3340 is a high performance integer-N PLL

capable of frequency synthesis up to 3.0 GHz. The

superior phase noise performance of the PE3340 makes

it ideal for applications such as wireless local loop

basestations, LMDS systems and other demanding

terrestrial systems.

The PE3340 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.

Fabricated in Peregrine’s patented UTSi® (Ultra Thin

Silicon) CMOS technology, the PE3340 offers excellent

RF performance with the economy and integration of

conventional CMOS.
