Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a precise 54.054 MHz clock source is required in space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital systems. Consider the small 2.0x1.6 mm form factor for high-density board layouts. Verify that the LVCMOS output interface matches the input requirements of the connected logic devices.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized small outline package. The 'PD' suffix indicates the inclusion of a power-down control pin, allowing for active management of power consumption during idle periods.

Oscillators Replacement Considerations

Direct replacements must match the 54.054 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package dimensions. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if specified in the original design documentation.
