Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's datasheet to confirm the exact enable pin configuration and tolerance specifications. Ensure the 1.8V supply requirement aligns with the target circuit design before procurement. Cross-reference the 4-SMD no-lead footprint dimensions with the PCB layout to guarantee mechanical compatibility.

Oscillators Selection Notes

Select this component when a 43.56 MHz clock signal is required with low voltage operation. Consider the enable/disable feature if power efficiency is critical. Compare the 2.0x1.6mm package size against available board space. Verify that LVCMOS output levels are compatible with the receiving logic inputs of the application.

Oscillators Part Context

This part belongs to the Mercury Electronics SMD oscillator series, which provides various frequency options in standardized packages. The 18QHTF21 series typically offers standard performance characteristics suitable for general-purpose timing applications. Other variants in this family may differ in frequency, voltage, or package type while maintaining similar functional architectures.

Oscillators Replacement Considerations

The 18QHTF21-43.560-PD is a documented alternative from the same manufacturer offering identical electrical specifications but potentially differing in packaging or ordering suffix details. Verify pinout and mechanical dimensions before substitution.
