89H48H12G3YAHLI8

Overview

The 89H48H12G3YAHLI8 is a 48-lane, 12-port PCI Express Gen3 system interconnect switch manufactured by Renesas Electronics Corporation. It delivers up to 96 GBps (768 Gbps) of switching capacity through integrated SerDes supporting 8.0 GT/s operation. The device features a non-blocking architecture with low latency cut-through and supports x8, x4, x2, and x1 port configurations. Packaged in a 27mm x 27mm 676-ball FCBGA, it provides multi-root support for up to 12 independent partitions and includes comprehensive reliability features such as SECDED ECC protection on internal RAMs.

Feature Summary

• High-performance non-blocking switch architecture optimized for high throughput and low latency peer-to-peer traffic flows
• Multi-root support enabling dynamic reconfiguration of up to 12 fully independent switch partitions
• Comprehensive Reliability, Availability, and Serviceability (RAS) including ECRC support and end-to-end data path parity protection

Applications

• Enterprise server system interconnects
• Storage area networks and intelligent I/O systems
• Communications infrastructure requiring high bandwidth

Procurement Notes

Verify the manufacturer designation carefully, as this component was originally developed by IDT before being acquired by Renesas Electronics. Confirm that the specific suffix matches the required package and temperature grade specifications for your design. Ensure compatibility with existing BIOS or driver initialization sequences.

Selection Notes

Select this component when designing systems requiring deterministic switching for multiple simultaneous traffic flows across PCIe Gen3 lanes. Consider its partitionable architecture if multi-root support is necessary. Evaluate the 676-ball FCBGA footprint requirements against available board space and layer count constraints.
