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.
