Procurement Notes

Verify the specific suffix 'B' against official Renesas documentation to confirm the exact variant specifications, as ordering suffixes may denote distinct manufacturing revisions or packaging configurations. Ensure compatibility with target system voltage requirements and thermal constraints before procurement. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability. Confirm that the selected component meets all necessary regulatory standards for the intended deployment environment.

Selection Notes

Select this component when designing systems requiring multi-lane PCIe connectivity up to Generation 6. It is suitable for applications needing flexible clock architecture support, including both common-clocked and separate-reference topologies. Consider the integrated termination resistors for board space optimization. Evaluate the power consumption profile against system thermal budgets. Ensure the 48-VFQFPN package dimensions align with the PCB layout constraints and assembly capabilities.
