Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm temperature range and packaging configuration. The 'AI' designation indicates industrial temperature operation (-40°C to +85°C). Confirm whether the required quantity necessitates tape and reel or bulk packaging options as specified in the official ordering guide.

Clock Buffers, Drivers Selection Notes

Select this component when designing systems requiring low-jitter distribution for signals up to 200 MHz. Ensure the power supply voltage remains within the 1.8 V to 3.3 V operational window. Verify that the load capacitance requirements align with the typical application diagrams provided in the datasheet to maintain signal integrity.
