PE3236 2.2 GHz Integer-N PLL For Low Phase Noise Applications

The PE3236 is a high performance integer-N PLL capable of frequency synthesis up to 2.2 GHz. The superior phase noise performance of the PE3236 is ideal for applications such as LMDS / MMDS / WLL basestations and demanding terrestrial systems. The PE3236 features a 10/11 dual modulus prescaler, Counters and a phase Comparator Counter values are programmable through either a serial or parallel Interface and CAN also be directly hard wired. This programming flexibility, combined with the dual latch architecture enabling ping-pong loading of the main divide Counter makes these PLLs well suited as the core for fractional-N or sigma-delta implementation. It is offered in a 44-lead PLCC package.
