The PE3341 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 PE3341 is ideal for
applications such as sonet, wireless base stations, fixed
wireless, and RF instrumentation systems.
The PE3341 features a ÷10/11 dual modulus prescaler,
counters, a phase comparator, and a charge pump as shown in
Figure 1. Counter values are programmable through a three-
wire serial interface.
The PE3341 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.
