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 layout accommodates the 2.0x1.6 mm SMD footprint and no-lead package specifications to guarantee proper soldering and thermal performance during assembly.

Oscillators Selection Notes

Select this model when a 24.883 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 due to the small 4-SMD package size. Compare against other Mercury oscillators if different frequencies or voltage levels are needed.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard crystal oscillators. The series offers various frequencies and voltage options within a consistent small form factor. The 'PD' suffix indicates the inclusion of power-down functionality. Mercury Electronics specializes in quartz crystals and frequency control products, providing reliable timing solutions for industrial and consumer applications.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical pinout and package but different frequencies, such as 18QHTF21-51.200-PD or 18QHTF21-6.000-PD, provided the frequency difference is acceptable for the application.
