PE3240

Peregrine's PE3240 is a high performance integer-N PLL capable of frequency synthesis up to 2.2 GHz.  The superior phase noise performance of the PE3240 is ideal for applications such as wireless local loop basestations, LMDS systems and other demanding terrestrial systems.
 
The PE3240 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.
 
The PE3240 is manufactured on Peregrine's UltraCMOS^TM process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs PE3240 with the economy and integration of conventional CMOS.
