Oscillators Procurement Notes

Verify the specific suffix codes against official SiTime documentation to confirm electrical parameters such as voltage, frequency stability, and output format. Ensure the ordering code matches the required package type and temperature grade. Cross-reference the part number with authorized distributors to confirm availability and authenticity. Request current datasheets to validate pinout configurations and thermal characteristics before finalizing procurement decisions.

Oscillators Selection Notes

Select this component when a programmable VCXO with differential LVDS outputs is required for applications needing wide pull ranges. Consider the ±800 ppm pull capability and ±50 ppm stability for systems sensitive to frequency modulation. Evaluate the 7.0mm x 5.0mm footprint against board space limitations. Confirm that the 3.3V supply requirement aligns with the system power architecture and that the -40°C to +85°C range meets environmental specifications.

Oscillators Part Context

This part belongs to the SiT3372 Elite Platform series, which utilizes silicon MEMS technology instead of traditional quartz. The series offers customizable frequency, stability, and voltage options, eliminating the need for custom quartz manufacturing. It is designed to replace standard oscillators in applications requiring high reliability and resistance to shock, vibration, and electromagnetic interference.

Oscillators Replacement Considerations

Direct replacements must match the MEMS VCXO topology, LVDS output, and 100MHz frequency. Verify compatibility of the ±800 ppm pull range and ±50 ppm stability. Ensure the replacement fits the 7.0mm x 5.0mm SMD package and operates within the same voltage and temperature limits.
