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 power rails. Ensure the 4-SMD footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 25.500 MHz clock source is required for LVCMOS-compatible devices. The choice is driven by the need for a low-profile 4-SMD package and the integration of enable/disable controls within a 1.8V operating environment. Consider thermal performance and size constraints relative to other available oscillator options.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage levels, all sharing the same compact 4-SMD form factor. This specific model provides a 25.500 MHz output, fitting into applications requiring stable timing signals in space-constrained designs.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical pinout and envelope but different frequencies or voltages, such as 18QHTF21-25.768-OE. Cross-brand replacements require matching LVCMOS logic, 1.8V supply, and 4-SMD dimensions.
