The SiT3907 is a highly flexible, high performance DCXO with LVCMOS/LVTTL compatible output. This programmable device supports any frequency, 1-220 MHz, along with any combination of voltage (1.8 V; 2.5 V to 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. It comes in 3 industry-standard package sizes, 4-pin 3.2x2.5 mm, and 6-pin 5.0x3.2 or 7.0x5.0 mm.
