Oscillators Procurement Notes

Verify the specific suffix (OE) against the manufacturer's current naming convention to ensure correct ordering. Confirm that the 1.8V supply voltage aligns with the target circuit design requirements. Check the package footprint dimensions (2.0x1.6mm) against the PCB layout specifications to ensure proper soldering and mechanical fit during assembly processes.

Oscillators Selection Notes

Select this component when a low-profile, low-voltage oscillator is required for space-constrained designs. Ensure the application supports LVCMOS logic levels and requires an active enable pin for power management. Compare against other models in the 18QHTF21 series if different frequencies or voltage levels are needed for the specific system architecture.

Oscillators Part Context

This part belongs to the 18QHTF21 series of low-voltage crystal oscillators from Mercury Electronics. The series typically includes various frequencies such as 10.58144 MHz and 44.2 MHz within the same physical package. These components are designed to provide stable clock signals for modern electronic devices while minimizing power usage and board space requirements.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-31.744-PD variant from the same manufacturer family. Other frequencies in the 18QHTF21 series may serve as functional replacements if the system allows for frequency adjustment. Verify pinout and electrical characteristics before swapping with generic LVCMOS oscillators.
