Product Description
Peregrine’s PE97632 is a radiation tolerant, high
performance fractional-N PLL capable of frequency
synthesis up to 3.5 GHz. The device is designed for
commercial space use and optimized for superior phase
noise performance while providing an order of magnitude
reduction in current consumption, when compared with
existing commercial space PLLs.
The PE97632 features a ÷10/11 dual modulus prescaler,
counters, a delta sigma modulator and a phase comparator
as shown in Figure 1. Counter values are programmable
through a serial or direct hardwired mode.
The PE97632 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.
