The SiT9120 is a fixed frequency, ultra performance, Differential Oscillator that supports LVPECL and LVDS output signaling types. This differential oscillator covers most commonly used frequencies between 25 MHz to 212.5 MHz, with best-in-class RMS phase jitter of 0.6 ps. Unlike quartz or SAW based traditional oscillators, the SiT9120 is available in any combination of voltage (2.5V to 3.3V), frequency stability (±20, ±25, and ±50 PPM) and package (3225, 5032, 7050) options.
