220到625 MHz, Differential Digitally-controlled XO

The SiT3922 is a highly flexible, high-frequency differential MEMS DCXO that supports LVPECL and LVDS outputs. This programmable device supports any frequency, 1 to 220 MHz, along with any combination of voltage (1.8 V; 2.5 V to 3.3 V), pull range (±25 ppm to ±1600 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. It comes in 3 industry-standard 6-pin packages (3.2x2.5 mm, 5.0x3.2 mm, 7.0x5.0 mm).
