SiTime Corporation Digitally Controlled Oscillators SiT3907AI-23-33NY-12.000000

The SiT3907 is a high-precision digitally controlled oscillator (DCXO) supporting output frequencies from 1 MHz to 220 MHz, with a programmable pull range up to ±1600 PPM and frequency stability options of ±10, ±25, or ±50 PPM. It operates from supply voltages of 1.8 V, 2.5 V, 2.8 V, or 3.3 V and is available in three surface-mount packages: 3.2 mm × 2.5 mm (4-pin), 5.0 mm × 3.2 mm (6-pin), and 7.0 mm × 5.0 mm (6-pin). The device features a tri-level digital programming interface, low RMS jitter of 1.5-3 ps, and a start-up time of 6-10 ms, with an aging rate of ±5 PPM over 10 years. It meets MIL-STD-883F, JESD22, and MSL1 standards for mechanical and environmental reliability. The part specified is an industrial-grade variant with ±50 PPM stability, 3.3 V supply, and a 6-pin 5.0 mm × 3.2 mm package with the DP pin disabled.
