• Communication equipment signal processing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 3.3V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm package dimensions to prevent assembly issues. Cross-reference the datasheet for operating temperature range compliance.

Selection Notes

Select this component when a standard LVCMOS clock source is required at 116.48 MHz. Consider the 3.3V operating voltage and the availability of the power-down pin for energy management strategies. Evaluate the small form factor suitability for high-density board layouts compared to larger oscillator packages.

Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within similar physical footprints. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from always-on variants in the same family.

Replacement Considerations

Direct substitutes may include other 116.48 MHz LVCMOS oscillators in 2.0x1.6mm packages from different manufacturers, provided electrical parameters match. Verify pin compatibility and voltage levels. No specific alternative part numbers are confirmed in public documentation.
