Procurement Notes

Verify the exact suffix against official documentation, as variations may exist. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Check for obsolescence notices or lifecycle changes directly from the manufacturer. Ensure ESD handling protocols are followed during assembly due to the sensitive nature of the internal circuitry.

Selection Notes

Select this component when a single-channel driver with 1.25 Gbps capability is required. Consider the 3V to 3.6V supply constraint and the specific 16-QFN footprint requirements. Evaluate thermal performance needs given the small package size and ensure the application environment stays within the specified operating temperature range.
