Description

Peregrine's PE3238 is a high performance integer-N PLL capable of frequency synthesis up to 1.5 GHz. The superior phase noise performance of the PE3238 is ideal for applications such as LMDS / MMDS / WLL basestations and demanding terrestrial systems.

The PE3238 features a 10/11 dual modulus prescaler, counters and a phase comparator as shown in Figure 1. Counter values are programmable through either a serial or parallel interface and PE3238 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 PE3238 well suited as the core for fractional-N or sigma-delta implementation.

The PE3238 is optimized for terrestrial applications. PE3238 is manufactured on Peregrine's UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
