PE3342
Product Description
Peregrine’s PE3342 is a high performance integer-N PLL with embedded EEPROM capable of frequency synthesis up to 2700 MHz with a speed-grade option to 3000 MHz. The EEPROM allows designers to permanently store control bits, allowing easy configuration of self-starting synthesizers. The superior phase noise performance of the PE3342 is ideal for applications such as wireless base stations, fixed wireless, and RF instrumentation systems. The PE3342 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 PE3342 UltraCMOS Phase Locked-Loop is manufactured in Peregrine’s patented Ultra Thin Silicon (UTSi) CMOS process, offering excellent RF performance with the economy and integration of conventional CMOS.
