Product Description
Peregrine’s PE9702 is a high-performance integer-N PLL
capable of frequency synthesis up to 3000 MHz. 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 PE9702 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 PE9702 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.
