PE9701 Datasheet, PDF (1/13 Pages) Peregrine Semiconductor Corp. – 3000 MHz UltraCMOS™ Integer-N PLL Rad Hard for Space Applications

Product Description
Peregrine’s PE9701 is a high-performance integer-N PLL
capable of frequency synthesis up to 3.0 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 PE9701 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 PE9701 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.
