PE3340
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.
