PE97640

Peregrine’s PE97640 is a radiation tolerant, high performance fractional-N PLL capable of frequency synthesis up to 5 GHz. The device is optimized for commercial space applications and superior phase noise performance.

The PE97640 features a 5/6 or 10/11 dual modulus prescaler, counters, a delta sigma modulator, a phase comparator and charge pump as shown inFigure 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.
