Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail is stable within the operational limits defined in the official datasheet to ensure reliable oscillator performance and longevity.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and power-down capability is required. Ensure the application board layout accommodates the 4-SMD no-lead footprint dimensions. Validate that the LVCMOS output swing matches the input thresholds of the connected load devices.

Oscillators Part Context

This part belongs to the Mercury Electronics standard XO series, which provides basic clock generation solutions. The model number indicates a 27.25 MHz frequency variant with OE suffix denoting the enable pin configuration. It serves as a fundamental timing source for systems requiring moderate precision without temperature compensation.

Oscillators Replacement Considerations

Direct substitutes must match the 27.25 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering identical electrical specifications and mechanical dimensions to ensure seamless integration.
