Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your circuit design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout to avoid assembly issues. Cross-reference the manufacturer's datasheet for detailed electrical characteristics and reliability data.

Selection Notes

Select this component when a precise 65.55 MHz clock source is required for low-voltage digital circuits. The LVCMOS output ensures compatibility with standard logic families. Consider the enable/disable feature if power efficiency is critical. Verify temperature range and stability requirements against application needs. Compare package dimensions with available board space constraints.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes specific packaging or tape-and-reel configuration details as per manufacturer standards. These oscillators are designed for high-frequency stability in compact electronic designs.

Replacement Considerations

Direct substitutes include other 65.55 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Ensure equivalent supply voltage (1.8V) and output logic levels. Verify pinout compatibility and thermal performance. Check for identical enable/disable functionality if required. Consult official cross-reference lists for validated replacements.
