Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required frequency and package specifications. Confirm that the manufacturer designation matches Mercury Electronics Ind. Co., Ltd. to avoid counterfeit components. Check datasheet revisions for any updates on electrical characteristics or mechanical dimensions before finalizing procurement decisions.

Oscillators Selection Notes

Select this component when a 40.675 MHz clock signal is required with minimal footprint. The 1.8V supply requirement suits modern low-voltage digital logic families. Ensure the system design accommodates the standby control feature if power management is a priority. Verify that the LVCMOS output levels are compatible with the receiving input thresholds.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6 mm package. The 'PD' suffix typically indicates the inclusion of a power-down pin or function, distinguishing it from standard continuous-operation variants.

Oscillators Replacement Considerations

Direct replacements must match the 40.675 MHz frequency, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility for the enable/disable or power-down control signals. Cross-reference with other manufacturers offering similar small-form-factor LVCMOS oscillators.
