The PE9704 features a 10/11 dual modulus prescaler, counters, and a phase comparator as shown in Figure 1. Counter values are programmable through a serial interface, and can also be directly hard wired. The PE9704 is optimized for commercial space applications. Single Event Latch-up (SEL) is physically impossible and Single Event Upset (SEU) is better than 10-9 errors per bit / day. Fabricated in Peregrine's patented UTSi (Ultra Thin Silicon) CMOS technology, the PE9704 offers excellent RF performance and intrinsic radiation tolerance.
