PE97632DIE - Fractional-N Frequency Synthesizer

General 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.

Key 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.

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.
