PE3238 General 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 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.

The PE3238 is optimized for terrestrial applications. It 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.

PE3240 General Description

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 with the economy and integration of conventional CMOS.
