Product Description
Peregrine’s PE9601 is a high performance integer-N PLL
capable of frequency synthesis up to 2.2 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 PE9601 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 PE9601 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 PE9601 offers excellent RF performance and intrinsic
radiation tolerance.
