Oscillators Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct output logic, voltage levels, and packaging options. Confirm that the selected variant matches the required APR and stability specifications for the target application environment. Cross-reference the part number with authorized distributors to validate current availability and authenticity before finalizing procurement orders.

Oscillators Selection Notes

Select this component when differential LVPECL outputs are required alongside MEMS reliability benefits. Ensure the system design accommodates the specified 3.0 V nominal supply voltage and the ±50 ppm pull range. Verify that the 3.2x2.5 mm footprint fits the PCB layout constraints and that the operating temperature range meets the environmental requirements of the end product.

Oscillators Part Context

This model belongs to the SiT3372 Elite Platform series, which focuses on differential MEMS VCXOs designed for low-jitter applications. The series provides alternatives to traditional quartz oscillators by offering superior robustness against mechanical stress and environmental variations while maintaining precise frequency control in compact form factors.

Oscillators Replacement Considerations

Direct replacements must match the 50 MHz frequency, LVPECL output, 3.0V supply, and 3.2x2.5mm package. Verify APR and stability specs. Consult SiTime documentation for cross-referencing compatible variants within the same platform family.
