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.
