Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 30.22 MHz frequency. Consider the small form factor suitable for dense board layouts. Evaluate the need for power-down capabilities if battery life or thermal management is critical. Compare alternative frequencies within the same series if exact matching is not mandatory.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various standard XO options. The series typically provides LVCMOS outputs in compact packages. Other variants in this line differ primarily in frequency settings while maintaining similar electrical characteristics and physical dimensions for consistent design integration across different product lines.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical pinouts but different frequencies, such as 18QHTF21-30.300-PD or 18QHTF21-51.200-PD, provided the frequency difference is acceptable for the application.
