Procurement Notes

Verify the specific ordering suffix 'OE' against the manufacturer's current documentation to ensure correct configuration. Confirm that the 1.8V supply requirement aligns with the target system design. Check the datasheet for precise operating temperature ranges and load capacitance requirements before finalizing the bill of materials.

Selection Notes

Select this component when a 62.3 MHz timing source is required with low-voltage operation. Ensure the application supports LVCMOS logic levels and can provide the necessary enable signal. Consider the physical dimensions of the 4-SMD package for PCB layout constraints and thermal management requirements during the design phase.

Part Context
