Oscillators Procurement Notes

Verify the complete part number against official SiTime documentation to ensure correct configuration parameters including voltage, output type, and frequency. Confirm that the specific suffix matches the required operational specifications for your design. Cross-reference with authorized distributors to validate authenticity and availability status before finalizing procurement orders.

Oscillators Selection Notes

Select this component when low-jitter differential clocking is required alongside voltage-controlled frequency adjustment capabilities. The integrated regulation simplifies board design by removing the need for separate linear regulators. Ensure the application environment falls within the specified industrial temperature range and that the LVPECL interface is compatible with the receiving logic inputs.

Oscillators Part Context

This model belongs to the SiT3372 Elite Platform series, designed as a high-performance alternative to traditional quartz VCXOs. The series leverages MEMS technology to offer superior resilience to mechanical stress and environmental changes compared to bulk acoustic wave devices. It supports rapid customization through factory programming, reducing lead times associated with custom quartz manufacturing.

Oscillators Replacement Considerations

Direct replacements must match the 173.37075 MHz frequency, LVPECL output, and 2.8V supply requirements. Verify pinout compatibility and package dimensions (7.00mm x 5.00mm) for existing footprints. Consider other SiT3372 variants if different stability or pull ranges are acceptable, but ensure the core MEMS architecture aligns with system jitter and phase noise specifications.
