Procurement Notes

Verify the specific suffix ZDBLG8 against official Renesas documentation, as standard listings often reference ZCBLGI or ZBHLI variants. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements prior to handling. Check for end-of-life notices or alternative package options if current stock is limited.

Selection Notes

Select this component when a non-blocking 12-port PCIe Gen2 switch is required for deterministic system interconnect. Ensure the design accommodates the 676-FCBGA footprint and supports the necessary 1V, 2.5V, and 3.3V power rails. Verify that the application benefits from partitionable architecture for multi-root support.
