89H48H12G2ZCBL

Overview

The 89H48H12G2ZCBL is a discontinued PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 48 lanes and 12 ports of high-performance, deterministic switching with non-blocking architecture. The device operates within a commercial temperature range of 0°C to 70°C and utilizes a 676-FCBGA package measuring 27x27 mm. It supports multiple voltage domains including 1V, 2.5V, and 3.3V, ensuring compatibility with various system requirements while maintaining low latency and power consumption.

Feature Summary

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

Applications

• High-performance computing system interconnects
• Multi-root server configurations requiring partitionable switching
• Storage area network infrastructure

Procurement Notes

This component is officially classified as obsolete and no longer in production. Verification of availability should focus on surplus distributors or secondary market sources rather than authorized manufacturer channels. Buyers must confirm the specific revision level and physical condition of the unit prior to acquisition, as stock levels vary significantly across different suppliers.

Selection Notes

Engineers replacing this part should evaluate current-generation PCIe switches that offer equivalent lane counts and port densities. Compatibility checks must include pinout alignment and thermal management requirements due to the FCBGA packaging. Software drivers and configuration tools associated with legacy devices may require updates to function correctly with newer silicon generations.

Part Context

This part belongs to the PES48H12G2 family of PCIe switches, which were widely used in enterprise server architectures before the transition to PCIe Gen3 and Gen4 standards. The ZCBL suffix indicates a specific package variant and lead-free composition compliant with environmental regulations active during its production lifecycle.

Replacement Considerations

Direct pin-to-pin replacements are not available due to architectural advancements in newer PCIe generations. Suitable alternatives include the 89HPES48T12G2 series or other modern PCIe switches from Renesas and competitors offering comparable port counts.
