89H48H12G3YBHLG8

Overview

The 89H48H12G3 is a 48-lane, 12-port PCI Express Gen3 system interconnect switch designed for high-performance applications. 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 complies with the PCI Express Base Specification 3.0 and includes Advanced Error Reporting, Atomic operations, and Multi-Root support.

Feature Summary

• High-performance non-blocking switch architecture optimized for multi-root systems
• Integrated SerDes supporting PCIe Gen3, Gen2, and Gen1 speeds
• Multi-Root support enabling up to 12 independent switch partitions
• RAS features including SECDED ECC protection and end-to-end parity

Applications

• Enterprise servers requiring high throughput interconnects
• Storage arrays and intelligent I/O systems
• Communications infrastructure with inter-domain communication needs
• Embedded systems utilizing multiple peer-to-peer traffic flows

Procurement Notes

Verify component authenticity by checking manufacturer markings against official documentation. Confirm package integrity and pin alignment prior to installation. Ensure compliance with RoHS directives if required by your specific application environment. Review the datasheet for handling precautions related to the FCBGA package and moisture sensitivity levels.

Selection Notes

Select this component when designing systems requiring deterministic switching for multiple simultaneous data streams. It is suitable for architectures needing partitionable switches for true multi-root support. Consider its compatibility with standard PCIe Gen3 interconnects for efficient board layout. Evaluate its power management capabilities against system thermal constraints.

Part Context

Originally developed by Integrated Device Technology (IDT), this part belongs to the 89H48H12 series of PCIe switches. IDT was acquired by Renesas Electronics Corporation, which now manages the product line. This generation of switches bridges legacy Gen2 designs with modern Gen3 requirements, offering backward compatibility while providing enhanced bandwidth.

Replacement Considerations

The 89H48H12G2 serves as a previous generation alternative supporting PCIe Gen2 speeds. While functionally similar in port count, it offers lower bandwidth. Verify software toolchain compatibility, such as the PCIe Browser Software, when transitioning between generations.
