PE97632DIE Datasheet, PDF (1/16 Pages) Peregrine Semiconductor – 3.5 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 the 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 either a serial interface or directly hard-wired.
The PE97632 is optimized for commercial space
applications. Single event latch-up (SEL) is physically
impossible. Fabricated in Peregrine’s patented UltraCMOS^®
technology, the PE97632 offers excellent RF performance
and intrinsic radiation tolerance.
