Oscillators Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's official documentation to ensure compatibility with your design requirements. Confirm that the 1.8V supply voltage and LVCMOS output levels align with your target circuit specifications before finalizing procurement decisions.

Oscillators Selection Notes

Select this component when a 54.36125 MHz clock source is required within a 1.8V operating environment. Ensure the PCB layout accommodates the 2.0x1.6mm SMD footprint. Consider the standby feature if power efficiency during idle states is a critical design parameter for the application.

Oscillators Part Context

This part belongs to the QHTF series of standard oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within small form factors. The 'PD' suffix likely indicates the power-down capability, distinguishing it from continuous operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 54.36125 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics with alternative manufacturers before substitution.
