PE33241 Datasheet, PDF (1/13 Pages) Peregrine Semiconductor – UltraCMOS Integer-N PLL Frequency Synthesizer for Low Phase Noise Applications

Product Description
Peregrine’s PE33241 is a high-performance Integer-N
PLL capable of frequency synthesis up to 5 GHz. The
device is designed for superior phase noise performance
with a direct or serial programming option.
The PE33241 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.
