Product Specification
PE9704
Product Description
Peregrine’s PE9704 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 PE9704 features a ÷10/11 dual modulus prescaler,
counters, and a phase comparator as shown in Figure 1.
Counter values are programmable through a serial
interface, and can also be directly hard wired.
The PE9704 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.
