Oscillators Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the selected variant matches the required supply voltage and output logic levels for the target application circuit. Cross-reference the package dimensions to confirm PCB footprint alignment.

Oscillators Selection Notes

Select this component when low jitter and high immunity to environmental stressors are critical. The integrated regulation simplifies power design by removing external components. Confirm that the ±35 ppm pull range meets the system's frequency tuning requirements and that the LVPECL interface is compatible with the receiving logic.

Oscillators Part Context

This part belongs to the SiT3372 family of ultra-low jitter differential VCXOs from SiTime. These devices are engineered for applications demanding exceptional dynamic performance and reliability in harsh environments, leveraging silicon MEMS technology instead of traditional quartz.

Oscillators Replacement Considerations

Direct replacements must match the 160 MHz frequency, LVPECL output, 2.8V supply, and 6-SMD package. Verify if alternative SiTime models offer compatible pull ranges and stability specifications without requiring schematic changes.
