SiT9122中文资料220 to 625 MHz, ±10 to ±50 ppm Differential XO数据手册SiTime规格书

描述 Description

The 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 to 625 MHz, with RMS phase jitter of 0.6 ps (typ.). 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, ±20, ±25, and ±50 ppm) and package (3225, 5032, 7050) options.
