PE9763

Peregrine's PE9763 is a high performance fractional-N PLL capable of frequency synthesis up to 3.2 GHz. The PE9763 is designed for superior phase noise performance while providing an order of magnitude reduction in current consumption, when compared with the existing commercial space PLLs.

The PE9763 features a 10/11 dual modulus prescaler, counters, a delta sigma modulator, a phase comparator and a charge pump as shown in Figure 1. Counter values are programmable through either a serial interface or directly hardwired. PE9763 is optimized for commercial space applications.

Single Event Latch up (SEL)PE9763 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 PE9763 offers excellent RF performance and intrinsic radiation tolerance.
