Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations required by your application environment to guarantee reliable performance.

Oscillators Selection Notes

Select this component when a precise 27.683055 MHz clock source is needed with low profile packaging. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the enable pin feature if power management or clock gating is required in the design. Verify that the 1.8V operating voltage meets the target system specifications.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and enable features. These components are designed for high-reliability applications in consumer electronics and industrial systems where space-saving SMD packages are preferred over through-hole alternatives.

Oscillators Replacement Considerations

Direct substitutes include other 27.683055 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation.
