The SiT3922 is a 220 to 625 MHz digitally controlled oscillator (DCXO). It offers differential signaling with LVPECL and LVDS outputs, supply voltage options (1.8 V, or 2.5 V to 3.3 V), pull range (from ±25 ppm to ±200 ppm), and 3 packages (3225, 5032, or 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.
