89H48H12G3YBHL

Overview

The 89H48H12G3YBHL 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 PCIe Base Specification 3.0 standards including Advanced Error Reporting and Atomic operations. Packaged in a 27mm x 27mm 676-ball FCBGA, it enables multi-root support with up to 12 independent partitions and includes RAS features like SECDED ECC protection.

Feature Summary

• High-performance non-blocking switch architecture optimized for high throughput and low latency
• Multi-root support allowing up to 12 fully independent switch partitions with dynamic reconfiguration
• Comprehensive Reliability, Availability, and Serviceability features including ECRC and SECDED ECC protection
• Supports multiple port configurations including x8, x4, x2, and x1 lanes with automatic negotiation

Applications

• Enterprise server system interconnect
• Storage area networks and SSD storage arrays
• Communications infrastructure systems
• Multi-host or intelligent I/O based systems requiring inter-domain communication

Procurement Notes

Verify the specific ordering suffix YBHL against official documentation to confirm package type and temperature grade. Confirm current availability status as product lifecycles may change. Ensure compatibility with existing root complex designs before procurement.

Selection Notes

Select this component for applications requiring high bandwidth and deterministic switching performance. Consider the 676-ball FCBGA package constraints during PCB layout. Evaluate thermal requirements given the high-speed SerDes operation at 8.0 GT/s.

Part Context

This part belongs to the IDT 89H series of PCIe switches, designed for high-end enterprise and storage applications. It represents an evolution from previous Gen2 generations, offering doubled lane speeds while maintaining similar port counts and partitioning capabilities.

Replacement Considerations

Direct replacements include the 89H48H12G2 for Gen2 applications, though speed differences must be accounted for. Verify pinout and register compatibility if migrating from older switch architectures.
