Procurement Notes

Verify the specific suffix ZBBCGI8 against official Renesas documentation to confirm package type and temperature grade. Check current product status as this series may be obsolete or end-of-life. Confirm availability through authorized distributors only. Ensure compatibility with existing PCIe Gen2 host controllers. Review datasheet for pinout and electrical specifications before integration.

Selection Notes

Select this component when 12-port PCIe Gen2 switching is required for non-blocking data throughput. Consider its partitionable architecture if multi-root support is necessary for the system design. Evaluate the need for movable upstream and NTB functions for complex topology requirements. Compare against newer generations if future scalability is a priority, as older switches may have limited supply.
