SiTime's SiT9122 is a highly flexible, high frequency, programmable differential oscillator that supports LVPECL and LVDS output signaling types. This differential oscillator covers any frequency between 220 MHz and 625 MHz, with best-in-class RMS phase jitter of 0.6 ps. Unlike quartz or SAW based traditional oscillators, the SiT9122 is available in any combination of voltage (2.5 V to 3.3 V), frequency stability (±10 ppm, ±20 ppm, ±25 ppm, and ±50 ppm), and package (3225, 5032, 7050) options.
