Oscillators Procurement Notes

Verify that the specific part number includes the OE suffix to confirm the presence of the enable/disable pin functionality. Ensure the required supply voltage matches the 1.8V specification. Confirm the package type aligns with the PCB footprint design. Cross-reference the frequency tolerance requirements against application needs before ordering.

Oscillators Selection Notes

Select this component when a 24.9 MHz clock source with active low or high enable control is required. The LVCMOS output ensures compatibility with standard digital logic families. Consider the 1.8V operating voltage constraint during power budget analysis. The small 2.0x1.6 mm package is suitable for space-constrained designs.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, characterized by its 1.8V operation and small SMD footprint. The series offers various frequencies and control options, with the OE variant specifically providing enable/disable capabilities. It serves as a timing solution for modern low-voltage digital applications.

Oscillators Replacement Considerations

Direct substitutes must match the 24.9 MHz frequency, 1.8V supply, LVCMOS output, and enable/disable function. Verify package dimensions (2.0x1.6mm) and pinout compatibility. Check datasheets for equivalent parts from other manufacturers offering similar timing specifications and control features.
