Additional preview pages of the PE97640 datasheet.

The PE97640 is a radiation tolerant, high performance, fractional-N PLL capable of frequency synthesis up to 5 GHz.

a 5/6 or 10/11 dual modulus prescaler, counters, a delta sigma modulator, a phase comparator and charge pump as shown in Figure 1. Counter values are programmable through either a serial interface or directly hard-wired. The PE97640 is available in a 64-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.
