SiT3921 Datasheet

The SiT3921 is a 1 to 220 MHz digitally controlled oscillator (DCXO). This differential oscillator supports LVPECL and LVDS outputs, any frequency along with any combination of voltage (1.8 V, 2.5 V-3.3 V), pull range (±25 ppm to ±200 ppm), and package (3225, 5032, 7050). It enables frequency tuning via a unique one-wire interface, eliminating frequency drift that is caused by board noise and simplifying PLL and clock synchronization design.
