89H48H12G2ZDBL

Overview

The 89H48H12G2ZDBL is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, designed for high-performance system interconnect switching. It provides 48 PCI Express Gen2 lanes and supports 12 switch ports within a non-blocking architecture. The device utilizes a 676-ball FCBGA package with dimensions of 27x27 mm. It operates on a 3.3V supply voltage and is characterized for commercial temperature ranges. This component facilitates deterministic data transfer across multiple traffic flows without blocking, ensuring full line-rate throughput regardless of switch loading conditions.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support capabilities
• Internal buffering and flow control credits optimized for maximum bandwidth and large payloads

Applications

• High-performance system interconnect switching
• Multi-root server configurations
• Storage area network infrastructure

Procurement Notes

Verify the specific suffix ZDBL against official Renesas documentation to confirm exact temperature grade and lead-free status. Confirm current product lifecycle status as this series has faced discontinuation notices. Ensure compatibility with existing PCB footprints and power delivery requirements before procurement planning.

Selection Notes

Select this component when a non-blocking PCIe Gen2 switch with 12 ports is required for deterministic latency. Compare against partitionable alternatives if multi-root support is essential. Verify package availability and thermal dissipation requirements for the 676-FCBGA form factor in the target design environment.
