89H48H12G3YCHL8

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 supports x8, x4, x2, and x1 port configurations with automatic link width negotiation. Packaged in a 27mm x 27mm 676-ball FCBGA, it features non-blocking architecture, multi-root support for up to 12 independent partitions, and comprehensive reliability mechanisms including SECDED ECC protection on internal RAMs.

Feature Summary

• High-performance non-blocking switch architecture optimized for multiple simultaneous 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) features including ECRC and end-to-end data path parity
• Flexible initialization options supporting Root complex, Serial EEPROM, pin strapping, or SMBus configuration

Applications

• Enterprise servers requiring high throughput and low latency interconnects
• Storage arrays and intelligent I/O systems with inter-domain communication needs
• Communications infrastructure utilizing multi-host architectures

Procurement Notes
