PE3339 Datasheet, PDF (1/12 Pages) Peregrine Semiconductor Corp. – 3.0 GHz Integer-N PLL for Low Phase Noise Applications
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.
