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 SMD package dimensions. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure joint integrity.

Oscillators Selection Notes

Select this component when a 54.08 MHz clock source is required with low voltage operation. Consider the LVCMOS output swing levels to ensure compatibility with downstream logic families. Evaluate the need for standby control signals if power management is a priority. Compare physical size constraints against alternative packages in the same series.

Oscillators Part Context

This part belongs to the QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a small form factor. The 'PD' suffix indicates the presence of a power-down feature. This model specifically targets applications needing a stable 54.08 MHz reference in portable or space-constrained devices.

Oscillators Replacement Considerations

Direct substitutes may include other 54.08 MHz LVCMOS oscillators in 4-SMD packages from different manufacturers, provided pinouts and electrical specifications match. Verify equivalent frequency stability and phase noise characteristics. Cross-reference with similar Mercury models like the 18QHTF21-54.080-OE if lead-free or specific packaging variations are needed.
