89H48H12G2ZDBLI8

Overview

The 89H48H12G2ZDBLI8 is a PCIe switch interface IC manufactured by Renesas Electronics. It provides 48 PCIe Gen2 lanes and 12 switch ports, utilizing a non-blocking architecture optimized for high-performance system interconnects. The device supports partitionable switch architecture for multi-root functionality and includes internal buffering with flow control credits to maximize bandwidth for large payloads. It operates within a temperature range of -40°C to +85°C and uses a 676-FCBGA package.

Feature Summary

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

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level (MSL 4) handling requirements during storage and assembly. Check for specific revision differences in the datasheet as the product has been discontinued.

Selection Notes

Select this component when 48 lanes of PCIe Gen2 connectivity are required in a single package. Ensure the host system supports the necessary power rails (1V, 2.5V, 3.3V) and fits the 676-FCBGA footprint. Consider the discontinuation status and lead times for legacy inventory if integrating into new designs.

Part Context

This part belongs to the 89HPES48H12G2 family of PCIe switches from Renesas (formerly IDT). It is designed for deterministic system interconnect switching, offering low latency and low power consumption compared to previous generations. The ZDBLI8 suffix indicates specific packaging and environmental qualifications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product is marked as obsolete, engineers should consult Renesas for recommended upgrades or alternative families that meet similar lane count and performance specifications.
