Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and frequency tolerance are selected. Confirm that the 1.8V supply voltage aligns with the target circuit design requirements before procurement. Ensure the enable/disable pin configuration matches the system control logic. Cross-reference the datasheet for absolute maximum ratings to prevent operational damage during integration.

Selection Notes

Select this component when a stable 116.64 MHz clock source is required for LVCMOS compatible circuits. Consider the 1.8V operating voltage constraint against available power rails. Evaluate the small 2.0x1.6mm footprint for space-constrained PCB layouts. Verify temperature range specifications if the application involves extreme environmental conditions beyond standard commercial ranges.
