Oscillators Procurement Notes

Verify the specific operating voltage requirements against your system design, as the datasheet indicates support for 1.8V but other voltages may be available in this series. Confirm the enable pin configuration matches your control logic levels. Ensure the 4-SMD footprint aligns with your PCB layout constraints. Check the manufacturer's latest documentation for any updates to the electrical characteristics or recommended soldering profiles to guarantee reliable assembly and long-term performance.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator is required for applications needing a 14.75 MHz reference. The LVCMOS output is appropriate for standard CMOS-compatible logic families. Consider the enable feature if power conservation during idle states is necessary. Evaluate the thermal performance and operating temperature range to ensure compatibility with the environmental conditions of the target application. Compare physical dimensions against space-constrained design requirements.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages within a consistent 4-SMD form factor. These oscillators are designed for general-purpose timing applications where size and cost efficiency are prioritized alongside basic stability. The 'OE' suffix typically denotes specific packaging or operational variants within the manufacturer's catalog structure.

Oscillators Replacement Considerations

Direct replacements must match the 14.75 MHz frequency, LVCMOS output, and 4-SMD package dimensions. Verify supply voltage compatibility and enable pin functionality. Cross-reference with other manufacturers offering similar XO specifications in the same footprint to ensure pinout and electrical parameter alignment.
