Oscillators Procurement Notes

Verify the specific frequency suffix (18.0633) and operating voltage (1.8V) against schematic requirements. Confirm the package footprint matches the 2.0x1.6mm SMD layout. Ensure the enable/disable pin configuration aligns with the host controller's GPIO capabilities before finalizing procurement.

Oscillators Selection Notes

Select this component when a precise 18.0633 MHz reference is required in space-constrained designs. The 1.8V operation suits low-power portable devices. Consider the enable feature if dynamic power management is necessary. Verify temperature range specifications against the intended operational environment to ensure stability.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies within a consistent 2.0x1.6mm form factor. These components are designed for general-purpose clocking applications requiring reliable frequency stability and low profile integration in modern electronic assemblies.

Oscillators Replacement Considerations

Direct substitutes include other 18.0633 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation, such as the 18QHTF21-18.0633 variant without the OE suffix if enable functionality is not critical. Cross-reference pinouts and electrical characteristics carefully.
