ADVANCE INFORMATION
PE9704
Product Description
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.
The PE9704 features a ÷10/11 dual modulus prescaler,
counters, a phase comparator, and a charge pump, 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. Fabricated in Peregrine’s
patented UTSi® (Ultra Thin Silicon) CMOS technology,
the PE9704 offers excellent RF performance and intrinsic
radiation tolerance.

When handling this UTSi device, observe the same
precautions that you would use with other ESD-
sensitive devices. Although this device contains
circuitry to protect it from damage due to ESD,
precautions should be taken to avoid exceeding the
rating specified in Table 4.
Latch-Up Avoidance
Unlike conventional CMOS devices, UTSi CMOS
devices are immune to latch-up.
