Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 3.3V operating voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to avoid assembly issues.

Oscillators Selection Notes

Select this component when a standard LVCMOS output is required for low-power applications. The integrated enable/disable feature allows for power management strategies. Consider the 3.3V supply constraint and the specific 7.9954 MHz frequency need for synchronization tasks.

Oscillators Part Context

This part belongs to the 3QHTF22 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options, including 2.5V variants. The 'PD' suffix typically indicates a specific packaging or tape-and-reel configuration, though exact details require datasheet confirmation.

Oscillators Replacement Considerations

Direct substitutes within the same series include other 3QHTF22 models with compatible frequencies and voltages. Cross-reference with similar LVCMOS XO packages from other manufacturers if Mercury parts are unavailable, ensuring pinout and electrical characteristics match.
