Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before procurement. Confirm that the 4-SMD package footprint matches the target PCB layout. Ensure the 1.8V supply voltage aligns with the system power architecture to guarantee proper operation of the LVCMOS outputs.

Oscillators Selection Notes

Select this component when a precise 26.72 MHz timing source is required within a constrained board area. The choice is appropriate for designs prioritizing low power usage through standby capabilities. Verify compatibility with the host controller's input voltage levels and ensure the manufacturing lead times meet project schedules.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6 mm form factor. The '-PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from standard continuous-operation variants in the same family.

Oscillators Replacement Considerations

Direct substitutes include other 26.72 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Ensure replacement parts match the 1.8V supply requirement and physical dimensions. Verify that alternative sources provide equivalent frequency stability and phase noise specifications.
