Product Description
Peregrine’s PE9763 is a high performance fractional-N PLL
capable of frequency synthesis up to 3.2 GHz. The device is
designed for superior phase noise performance while providing
an order of magnitude reduction in current consumption, when
compared with the existing commercial space PLLs.
The PE9763 features a 10/11 dual modulus prescaler,
counters, a delta sigma modulator, a phase comparator and a
charge pump as shown in Figure 1. Counter values are
programmable through either a serial interface or directly hard-
wired.
PE9763 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 PE9763 offers excellent RF performance and
intrinsic radiation tolerance.
