Oscillators Procurement Notes

Verify the specific suffix (OE) against the manufacturer's current datasheet to confirm pinout configuration and electrical tolerances. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the package dimensions with the PCB footprint library to guarantee mechanical fit during layout design.

Oscillators Selection Notes

Select this component when a 22 MHz clock source is required with low voltage operation. The LVCMOS output is suitable for standard logic families. Consider the enable function if power efficiency is critical. Compare physical dimensions against available board space constraints before finalizing the design.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF series of surface-mount oscillators. The series offers various frequencies and voltage options. The 18QHTF21 variant specifically denotes the 2.0x1.6mm package size. The OE suffix typically indicates specific packaging or testing configurations defined by the manufacturer.

Oscillators Replacement Considerations

Direct substitutes include other 22 MHz LVCMOS oscillators in 2.0x1.6mm packages from Mercury Electronics, such as the 18QHTF22 series if pinout compatibility allows. Verify that replacement parts match the 1.8V supply requirement and enable functionality.
