PE97022

Peregrine's PE97022 is a high-performance integer-N PLL capable of frequency synthesis up to 3500 MHz. The PE97022 is designed for superior phase noise performance while providing an order of magnitude reduction in current consumption, when compared with existing commercial space PLLs.

The PE97022 features a 10/11 dual modulus prescaler, counters and a phase comparator as shown in Figure 1. Counter values are programmable through either a serial or parallel interface and can also be directly hard wired.

The PE97022 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. PE97022 is manufactured on Peregrine's UltraCMOS™ process, a patented variation of silicon-oninsulator (SOI) technology on a sapphire substrate, offering excellent RF performance and intrinsic radiation tolerance.
