Oscillators Procurement Notes

Verify that the specific part number matches the required 44 MHz frequency and 1.8V operating voltage. Confirm the package type is 4-SMD No Lead (SMD2016-4P) to ensure PCB footprint compatibility. Check for the OE suffix indicating the enable pin configuration. Ensure the supplier provides official datasheets confirming LVCMOS output characteristics before finalizing procurement.

Oscillators Selection Notes

Select this component when a 44 MHz clock source is needed within a 1.8V system environment. The enable/disable feature makes it suitable for battery-operated applications where power conservation is critical. The small SMD2016-4P package is ideal for dense circuit boards. Ensure the load capacitance requirements of the host circuit align with the oscillator specifications to maintain frequency accuracy.

Oscillators Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-voltage crystal oscillators. The series typically offers various frequencies and packages, with the 18QHTF21 variant specifically designed for 1.8V operation. The 'OE' suffix denotes the inclusion of an output enable function, distinguishing it from standard continuous-output models in the same family.

Oscillators Replacement Considerations

Direct replacements must match the 44 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify that substitute parts also include the enable/disable control feature. Cross-reference pinouts to ensure compatibility with the existing PCB layout. Consult manufacturer substitution guides for electrically equivalent components.
