Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations if used in extreme environments.

Selection Notes

Select this component when a 13.533 MHz clock source is required with low voltage operation. Consider the LVCMOS output level compatibility with downstream logic families. Evaluate the need for power-down functionality to meet efficiency targets. Compare package dimensions against available board space to ensure mechanical fit within the assembly.

Part Context

This part belongs to the 18QHTF21 series of surface mount oscillators from Mercury Electronic. The series typically offers various frequencies with consistent electrical characteristics. The 'PD' suffix indicates the inclusion of a power-down pin or function. These components are designed for applications demanding reliable quartz-based timing solutions in consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 13.533 MHz LVCMOS oscillators in similar packages. Verify equivalent supply voltage and output drive strength. Cross-reference pinout configurations to ensure compatibility. Check manufacturer datasheets for thermal and electrical parameter matching.
