1 to 220 MHz, ±10 to ±50 ppm Differential XO
The SiT9121 is a highly flexible, programmable differential oscillator that supports LVPECL and LVDS output signaling types. This differential oscillator covers any frequency between 1 to 220 MHz, with RMS phase jitter of 0.6 ps (typ.). 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.
