89H48H12G3YAHL8

Overview

The 89H48H12G3 is a 48-lane, 12-port system interconnect switch optimized for PCI Express Gen3 packet switching. It delivers up to 96 GBps (768 Gbps) of aggregated, full-duplex switching capacity through 48 integrated serial lanes. Each lane supports 8 GT/s bandwidth and complies with the PCI Express Base Specification 3.0. The device features a non-blocking architecture with low latency cut-through switching and supports maximum payload sizes up to 2 KB. Packaged in a 27mm x 27mm 676-ball FCBGA, it targets high-performance servers, storage, and communications systems requiring efficient inter-domain communication.

Feature Summary

• High-performance non-blocking switch architecture supporting up to 96 GBps switching capacity
• Multi-root support enabling up to 12 fully independent switch partitions with dynamic reconfiguration
• Comprehensive Reliability, Availability and Serviceability (RAS) including SECDED ECC protection and Advanced Error Reporting
• Flexible initialization options via Root, Serial EEPROM, pin strapping, or SMBus without power sequencing requirements

Applications

• Enterprise servers requiring high throughput and low latency interconnects
• Storage arrays and intelligent I/O based systems
• Communications infrastructure with multi-host capabilities
• Embedded systems needing deterministic system interconnect switching

Procurement Notes
