PE3239

Peregrineís PE3239 is a high performance integer-N PLL capable of frequency synthesis up to 2.2 GHz.  The superior phase noise performance of the PE3239 is ideal  for applications such as wireless local loop basestations, LMDS systems and other demanding terrestrial systems.
 
 
 
The PE3239 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 Peregrineís patented UTSiAE (Ultra Thin Silicon) CMOS technology, the PE3239 offers excellent RF performance with the economy and integration of conventional CMOS.
