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 operational limits. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a 37.95762 MHz reference is required with strict 1.8V compatibility. Consider the ±50ppm stability limit for timing-sensitive applications. Evaluate the thermal performance within the -40°C to 85°C range against environmental conditions. Compare package size constraints against available board space for optimal layout efficiency.

Oscillators Part Context

This model belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'PD' suffix indicates the inclusion of a power-down control feature. This specific variant targets applications needing a balance between low power consumption and standard CMOS compatibility.

Oscillators Replacement Considerations

Direct substitutes must match the 37.95762 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering identical form-factor oscillators if Mercury Electronics availability is limited.
