Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 3.3V supply voltage aligns with your system's power rails. Ensure the PCB layout accommodates the 2.0mm x 1.6mm SMD package dimensions and soldering thermal profiles specified in the manufacturer datasheet.

Oscillators Selection Notes

Select this component when a precise 14.475 MHz reference is required in space-constrained designs. The LVCMOS output simplifies interfacing with standard digital logic families. Consider the power-down capability if battery life or thermal management is a critical constraint in the final application environment.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies within a standardized 4-SMD package form factor. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from continuous-operation variants within the same physical footprint family.

Oscillators Replacement Considerations

Direct substitutes must match the 14.475 MHz frequency, 3.3V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics of alternative sources to ensure functional equivalence without redesigning the host circuit board.
