ADVANCE INFORMATION

PE9704

3.0 GHz Integer-N PLL for Rad

Product Description

Hard Applications

Peregrine’s PE9704 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.

Features

• 3.0 GHz operation

• ÷10/11 dual modulus prescaler

• Phase detector output

• Serial interface or hardwired

programmable

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.

• Ultra-low phase noise

• SEU < 10^-9errors / bit-day

• 100 Krad (Si) total dose

• 44-lead CQFJ

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^-9errors per bit / day. Fabricated in Peregrine’s

patented UTSi® (Ultra Thin Silicon) CMOS technology,

the PE9704 offers excellent RF performance and intrinsic

radiation tolerance.
