SiTime Corporation Voltage-Controlled Oscillators SiT3373AC-4B3-33NC240.000000

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. This device supports frequency stability as low as ±15 ppm and achieves 0.225 ps RMS phase jitter over a 12 kHz to 20 MHz bandwidth. Operating temperature ranges include extended industrial environments from -40°C to 105°C. The part integrates on-chip regulators to suppress power supply noise, eliminating the need for an external LDO. The SiT3373AC-4B3-33NC240.000000 variant uses LVDS signaling, a 3.2 x 2.5 mm package, 3.3 V supply, and a ±100 ppm pull range, with output enable disabled. The series is factory-programmable for frequency, stability, voltage, and pull range options, enabling flexible clock configurations without custom builds.
