89H48T12G2ZDBL8

Overview

The 89H48T12G2ZDBL8 is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation. It functions as a PCI Express switch providing 48 lanes and 12 ports for high-performance system interconnects. The device utilizes a non-blocking architecture to ensure deterministic throughput across multiple traffic flows. It supports partitionable switch configurations for multi-root applications and incorporates internal buffering with flow control credits optimized for large payloads. The component is designed for low latency and power efficiency in demanding computing environments.

Feature Summary

• Provides 48 PCIe Gen2 lanes and 12 switch ports for high-performance system interconnect switching
• Features a non-blocking switch architecture optimized for deterministic throughput regardless of loading
• Supports partitionable switch architecture for true multi-root support
• Includes internal buffering and flow control credits optimized for maximum bandwidth and large payloads

Applications

• High Performance System Interconnect
• Multi-root server architectures
• Low latency data center switching

Procurement Notes

Verify the exact suffix and package type when sourcing, as variations exist within the 89H48 family. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for end-of-life notifications or discontinuation notices from the manufacturer prior to finalizing design-in decisions.

Selection Notes

Select this component when 48 PCIe Gen2 lanes are required in a single switch solution. Ensure the host system supports the necessary root complex capabilities for partitionable switches. Verify that the 676-FCBGA package fits the board layout constraints. Compare against the 89H12NT12G2 if fewer lanes are sufficient for the specific application needs.

Part Context

This part belongs to the Renesas 89H48 series of PCI Express switches. It is related to evaluation kits such as the 89KTPES48T12G2. The device is distinct from the 89H48H12G2 variant which may have different packaging or feature sets. It serves as a core connectivity component in high-end server and storage systems requiring extensive PCIe expansion.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider evaluating the 89H48H12G2ZCBLGI for similar functionality, though package and specific feature differences must be verified. Consult Renesas technical support for current alternative recommendations.
