SiTime Corporation Voltage-Controlled Oscillators SiT3373AI-1B3-25NH540.000000

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 is 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. The device offers frequency stability as low as ±15 ppm, supports operating temperatures from -40°C to 105°C, and achieves 0.225 ps RMS phase jitter (typical) over a 12 kHz to 20 MHz bandwidth. It integrates on-chip regulators to suppress power supply noise, eliminating the need for an external LDO. The part uses SiTime's DualMEMS® and TurboCompensation® technologies to mitigate performance degradation from airflow, thermal gradients, shock, and vibration. It supports LVPECL signaling with a 2.5 V supply, and includes a ±25 ppm pull range, with enable functionality not available in the 3.2 x 2.5 mm package.
