Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design specifications before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output levels are compatible with the receiving logic inputs to guarantee reliable signal integrity and proper operation within the intended application environment.

Selection Notes

Select this component when a fixed frequency of 81.80296 MHz is required with low-voltage operation. Consider the enable/disable feature if power conservation during idle states is necessary. Evaluate the small form factor against available PCB space constraints. Ensure the operating temperature range meets the environmental conditions of the final assembly to maintain frequency stability over time.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequencies within the SMD package family. This specific model provides a high-frequency option suitable for data communication or processing interfaces where precise timing is critical for synchronization and data transfer rates in modern electronic devices.

Replacement Considerations

Check for direct substitutes with identical frequency and package dimensions. Verify that alternative models support the same 1.8V supply and LVCMOS output characteristics. Ensure any replacement maintains the enable/disable pin configuration to preserve existing board functionality without redesigning the control circuitry.
