89H48H12BG2ZCBL

Overview

The 89H48H12BG2ZCBL 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 supports partitionable switch configurations for multi-root systems and includes internal buffering optimized for large payloads. It operates on 3.3V power supplies and is housed in a 676-ball FCBGA package measuring 27x27 mm.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput for multiple traffic flows regardless of load
• Partitionable design enabling true multi-root support for flexible system integration
• Internal buffering and flow control credits optimized for maximum bandwidth and large payload transfers

Applications

• High performance system interconnect switching
• Multi-root server architectures
• Storage area network (SAN) infrastructure

Procurement Notes

This component is officially obsolete and no longer in production. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer supply. Confirm RoHS compliance status and specific package revisions when sourcing from third-party vendors to ensure compatibility with existing designs.

Selection Notes

Designers requiring active replacement options must evaluate newer generations of PCIe switches as this part is end-of-life. Verify that alternative components support the required 12-port configuration and PCIe Gen2 specifications. Review updated datasheets for changes in pinout, power requirements, and thermal management compared to the legacy 89H48H12 series.

Part Context

The 89H48H12BG2ZCBL belongs to the IDT PES48H12G2 family of PCIe switches. This series was designed for high-throughput applications requiring low latency and deterministic performance. The 'ZCBL' suffix indicates specific packaging and lead-free characteristics within the broader product line.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult Renesas for current portfolio recommendations or evaluate competitive offerings from other manufacturers supporting PCIe Gen2 or Gen3 standards.
