Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V operating voltage aligns with your system's power rails. Ensure the 7.0x5.0mm footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics to guarantee compatibility.

Oscillators Selection Notes

Select this component when a 15MHz reference clock is required with low voltage operation. Consider the physical size constraints as the 7.0x5.0mm package is larger than standard SMD oscillators. Evaluate the need for power-down functionality if battery life or thermal management is critical. Verify signal integrity requirements for LVCMOS outputs in your specific application environment.

Oscillators Part Context

This model belongs to the 18QHTF21 series of XO oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The suffix PD indicates power-down support. This specific variant provides a 15MHz output, distinguishing it from other frequency options within the same product family.

Oscillators Replacement Considerations

Direct substitutes must match the 15MHz frequency, 1.8V supply, LVCMOS output, and 7.0x5.0mm package. Check for equivalent power-down functionality. Verify pinout compatibility if replacing with different manufacturers. Ensure frequency stability specifications meet original design requirements.
