Not recommended for new designs. Teledyne recommends the PE9702 as a possible replacement. The 9702 is pin for pin compatible with the 97022.
UltraCMOS® 3.5 GHz Integer-N PLL for Space Applications
Peregrine’s PE97022 is a high-performance integer-N PLL capable of frequency synthesis up to 3.5 GHz. The device 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. Counter values are programmable through either a serial or parallel interface and can also be directly hardwired. 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. It 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.
