SiTime Corporation Voltage-Controlled Oscillators SiT3373AI-4E9-28NX281.000000

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 7.0 x 5.0 mm, 5.0 x 3.2 mm, and 3.2 x 2.5 mm packages, with standard LVPECL, LVDS, or HCSL signaling. This device delivers 0.225 ps RMS phase jitter over 12 kHz to 20 MHz bandwidth and supports frequency stability as low as ±15 ppm across operating temperatures from -40°C to 105°C. It integrates on-chip regulators to suppress power supply noise, eliminating the need for an external LDO. The part operates at 2.8 V ±10%, with a pull range of ±80 ppm and an output enable function. The device utilizes DualMEMS® and TurboCompensation® technologies for enhanced resistance to shock, vibration, and thermal gradients.
