Differential Oscillator Package

ace-award-2012-finalistThe SiT9121 is a highly flexible, ultra performance, programmable Differential Oscillatorthat supports LVPECL and LVDS output signaling types. This differential oscillator covers any frequency between 1 to 220 MHz, with best-in-class RMS phase jitter of 0.6 ps. Unlike quartz or SAW based traditional oscillators, the SiT9121 is available in any combination of voltage (2.5V to 3.3V), frequency stability (±10, ±20, ±25, and ±50 PPM) and package (3225, 5032, 7050) options.
