PE97240 Datasheet, PDF (1/21 Pages) Peregrine Semiconductor – Radiation Tolerant UltraCMOS Integer-N Frequency Synthesizer for Low Phase Noise Applications

Product Description
Peregrine’s PE97240 is a radiation tolerant high-
performance Integer-N PLL capable of frequency
synthesis up to 5 GHz. The device is designed for
commercial space applications and optimized for
superior phase noise performance.
The PE97240 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 PE97240 is available in a 44-lead CQFP 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 and intrinsic radiation tolerance.
