Oscillators Procurement Notes

Verify the specific suffix OE against the manufacturer's official documentation to confirm exact electrical tolerances and operating temperature ranges. Ensure the target application supports the 1.8V supply voltage and LVCMOS logic levels. Confirm that the 4-SMD no-lead package footprint matches the PCB layout requirements. Cross-reference the part number with authorized distributors to ensure authenticity and traceability of the Mercury Electronics product.

Oscillators Selection Notes

Select this oscillator when a 35.772 MHz frequency is required with LVCMOS outputs. Consider the 1.8V supply constraint and the need for an enable/disable feature. Evaluate the 4-SMD no-lead package size against available board space. Compare performance specifications such as phase noise and stability if critical for the specific application environment.

Oscillators Part Context

This component belongs to the Mercury Electronics standard XO series. The brand specializes in quartz crystals and oscillators. The model indicates a specific frequency and package type within their catalog. It is distinct from TCXO or VCXO variants which offer temperature compensation or voltage control features not present in this standard oscillator model.

Oscillators Replacement Considerations

Direct substitutes must match the 35.772 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and electrical parameters before substitution. Generic replacements may differ in stability or package dimensions.
