89H48H12G3YBHL8

Overview

The 89H48H12G3YBHL8 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 full-duplex 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 for high-performance server and storage applications.

Feature Summary

• High-performance non-blocking switch architecture delivering 96 GBps switching capacity
• Multi-Root support enabling up to 12 fully independent switch partitions
• Comprehensive Reliability, Availability and Serviceability (RAS) features including SECDED ECC protection
• Flexible initialization options via Root, Serial EEPROM, pin strapping, or SMBus

Applications

• Enterprise servers requiring high throughput interconnects
• Storage arrays and intelligent I/O systems
• Communications infrastructure with multi-host requirements
• Embedded systems needing domain-based communication

Procurement Notes

Verify component authenticity using official Renesas documentation and serial number tracking. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Ensure compatibility with existing BIOS and driver environments for proper switch initialization and partition configuration.

Selection Notes

Select this component for designs requiring dense PCIe connectivity with minimal board layer count. Evaluate thermal management requirements for the 676-ball FCBGA package. Verify that the application benefits from Multi-Root capabilities and advanced error reporting features over simpler switch solutions.

Part Context

This part belongs to the IDT 89H48H12G3 family of PCIe switches, originally developed by Integrated Device Technology before its acquisition by Renesas. It serves as a core interconnect solution for expanding PCIe lane counts in complex system architectures.

Replacement Considerations

Consult official Renesas documentation for confirmed substitute part numbers within the same product family. Verify pinout and electrical parameter compatibility before implementing any alternative components.
