SiTime Corporation Voltage-Controlled Oscillators SiT3373AI-1B9-33NB281.000000

The SiT3373 is a 220 MHz to 725 MHz differential MEMS VCXO with ultra-low jitter, delivering 0.225 ps RMS phase jitter over 12 kHz to 20 MHz bandwidth. It supports frequency stability as low as ±15 ppm and operates across a temperature range of -40°C to 105°C. The device 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. This specific variant operates at 281.000000 MHz with a 2.8 V supply, LVPECL signaling, and a ±35 ppm pull range. It includes on-chip regulators to suppress power supply noise, eliminating the need for an external LDO.
