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's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific RoHS or environmental compliance certifications required by your procurement policy.

Selection Notes

Select this component when a 112.0 MHz clock source is required with LVCMOS outputs. Consider the 1.8V operating voltage to ensure compatibility with low-power logic families. Evaluate the small 2.0x1.6 mm package size for space-constrained designs. Verify that the enable/disable feature meets your system's power sequencing needs.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies with standardized LVCMOS outputs. These components are designed for applications requiring stable clock signals in compact form factors.
