Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational needs. Confirm that the 4-SMD no-lead package footprint aligns with your PCB layout constraints to ensure proper assembly and electrical connectivity.

Oscillators Selection Notes

Select this component when a precise 39.081 MHz reference is required for LVCMOS-compatible digital circuits. Consider the 1.8V operating voltage and compact 2.0x1.6 mm form factor for space-constrained designs. Evaluate the need for power-down capabilities if energy efficiency during idle states is a priority for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various standard frequencies with consistent LVCMOS outputs and low-voltage operation. The 'PD' suffix indicates the inclusion of a power-down control feature within this specific model variant.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants such as 18QHTF21-30.300-PD or 18QHTF21-6.760-PD, provided the frequency difference is acceptable. Verify pinout compatibility and package dimensions when considering alternative frequencies within the same family.
