The SiT3907 is a high-performance DCXO with LVCMOS/LVTTL compatible output. This high precision digitally-controlled oscillator is a highly flexible solution that 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 3 industry-standard package sizes (4-pin 3.2x2.5 mm, 6-pin 5.0x3.2, or 7.0x5.0 mm). 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.
