PE3340 Datasheet, PDF (1/12 Pages) Peregrine Semiconductor Corp. – 3.0 GHz Integer-N PLL for Low Phase Noise Applications

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.
