Oscillators Procurement Notes

Verify the specific ordering suffix and frequency tolerance against the official datasheet before procurement. Ensure the selected variant matches the required operating temperature range and supply voltage specifications. Confirm package dimensions align with PCB footprint requirements to prevent assembly issues during manufacturing.

Oscillators Selection Notes

Select this component when a 31.25 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V supply constraint and the need for power-down capabilities. Evaluate the 2.0x1.6mm footprint against available board space. Compare performance metrics such as phase noise and stability if critical for the specific application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor crystal oscillators. The series typically offers various frequencies and output types within similar physical dimensions. The 'PD' suffix indicates the inclusion of power-down control features, distinguishing it from continuous-operation variants in the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 31.25 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics before swapping manufacturers.
