PE33241_14 Datasheet, PDF (1/19 Pages) Peregrine Semiconductor – UltraCMOS® Integer-N PLL Frequency Synthesizer

Product Description
Peregrine’s PE33241 is a high-performance Integer-N
PLL capable of frequency synthesis up to 5 GHz. This
device is designed for use in industrial and military
applications, point-to-point radios, wireless infrastructure
and CATV equipment.
The PE33241 offers superior phase noise performance
with a direct or serial programming option. It features a
selectable prescaler modulus of 5/6 or 10/11, counters
and a phase comparator as shown in Figure 1. Counter
values are programmable through either a serial
interface or directly hard-wired.
The PE33241 is available in a 48-lead 7x7 mm QFN and
is manufactured on Peregrine’s UltraCMOS^® process, a
patented variation of silicon-on-insulator (SOI)
technology on a sapphire substrate, offering excellent
RF performance.
