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 rail is stable and within the operational limits specified in the official datasheet to ensure reliable oscillator performance and longevity.

Oscillators Selection Notes

Select this component when a precise 22.68 MHz reference is required in space-constrained designs. The small 2.0x1.6 mm footprint makes it suitable for high-density PCB layouts. Ensure the application supports LVCMOS logic levels and can accommodate the necessary power-down control signals if standby functionality is utilized.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies in a standardized 4-pin SMD package. The 'PD' suffix indicates the inclusion of a power-down pin, allowing for active standby modes to reduce power consumption during idle periods.

Oscillators Replacement Considerations

Direct replacements must match the 22.68 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering identical electrical specifications and mechanical dimensions.
