• Includes standby power-down capability
• Utilizes LVCMOS output interface

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 14.3187 MHz specification. Confirm the package type corresponds to the 2.0x1.6mm SMD footprint. Ensure the voltage rating aligns with the 1.8V system design requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 14.3187 MHz reference is needed in space-constrained designs. The 1.8V supply requirement dictates compatibility with low-power digital logic families. The small form factor supports high-density PCB layouts where larger oscillators cannot fit.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series includes various frequencies within a standardized 2.0x1.6mm package, allowing designers to maintain consistent board footprints across different timing requirements.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical 2.0x1.6mm packages and 1.8V LVCMOS outputs, such as the 18QHTF21-14.3359-OE, provided the frequency difference is acceptable for the application.
