PE97632 Datasheet, PDF (1/15 Pages) List of Unclassifed Manufacturers – 3.2 GHz Delta-Sigma modulated Fractional-N Frequency Synthesizer for Low Phase Noise Applications

Product Description
Peregrine’s PE97632 is a high performance fractional-N PLL
capable of frequency synthesis up to 3.5 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 PE97632 features a ÷10/11 dual modulus prescaler,
counters, a delta sigma modulator, and a phase comparator as
shown in Figure 1. Counter values are programmable through
a serial or direct hardwired mode.
The PE97632 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 UltraCMOS™ technology,
the PE97632 offers excellent RF performance and intrinsic
radiation tolerance.
