SiTime Corporation Voltage-Controlled Oscillators SiT3373AC-1B3-28NC307.695484

The SiT3373 is a 220 MHz to 725 MHz differential MEMS VCXO with ultra-low jitter, designed for telecom, networking, and industrial applications requiring precise clocking in noisy environments. It features ±0.225 ps RMS phase jitter over 12 kHz to 20 MHz bandwidth and frequency stability as low as ±15 ppm. The device supports wide temperature ranges from -40°C to 105°C and integrates on-chip regulators to eliminate the need for an external LDO. Available in industry-standard packages of 7.0 x 5.0 mm, 5.0 x 3.2 mm, and 3.2 x 2.5 mm, it offers programmable output signaling options including LVPECL, LVDS, and HCSL, with pull ranges up to ±3200 ppm. The specific variant SiT3373AC-1B3-28NC307.695484 operates at 307.695484 MHz with a 2.8 V supply and ±50 ppm pull range, housed in a 3.2 x 2.5 mm package with LVDS signaling and no output enable function.
