SiTime Corporation Voltage-Controlled Oscillators SiT3373AC-1B2-30NG281.000000

The SiT3373 is a 220 MHz to 725 MHz differential MEMS VCXO designed for low-jitter applications in telecom and networking. It supports frequency stability as low as ±15 ppm, operates from -40°C to 105°C, and delivers 0.225 ps RMS phase jitter (typical) over 12 kHz to 20 MHz. The device integrates on-chip regulators to suppress power supply noise, eliminating the need for an external LDO. Available in 7.0 × 5.0 mm, 5.0 × 3.2 mm, and 3.2 × 2.5 mm packages, it offers programmable LVPECL, LVDS, or HCSL signaling and supply voltages of 2.5 V, 2.8 V, 3.0 V, or 3.3 V. Pull range options extend up to ±3200 ppm. The specific variant SiT3373AC-1B2-30NG281.000000 uses a 3.2 × 2.5 mm package, LVPECL output, 3.0 V supply, ±25 ppm stability, and ±50 ppm pull range without output enable.
