• Embedded system clock generation

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 voltage aligns with the system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a 28.376 MHz clock source is required with LVCMOS compatibility. Consider the 1.8V operating voltage constraint and the need for power-down capabilities. Evaluate the physical space constraints to accommodate the small 4-SMD form factor. Compare against other frequencies in the 18QHTF21 series if different timing standards are needed.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies including 6 MHz, 8 MHz, 51.2 MHz, and others, all sharing similar packaging and electrical characteristics. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from standard continuous-operation variants within the same product line.

Oscillators Replacement Considerations

Direct replacements include other frequencies within the 18QHTF21 series such as 18QHTF21-51.200-PD or 18QHTF21-96.768-PD, provided the frequency difference is acceptable. Verify pinout compatibility and thermal performance when substituting with different models from the same manufacturer.
