89H64H16AG2ZDBLI

Overview

The 89H64H16AG2ZDBLI is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, designed as a high-performance system interconnect switch. It provides 64 PCIe Gen2 lanes and 16 switch ports within a non-blocking architecture optimized for deterministic data throughput. The device operates on a 3.3V supply voltage and utilizes a 324-FCBGA package with dimensions of 19x19 mm. This component supports internal buffering and flow control credits to maximize bandwidth efficiency.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput for multiple traffic flows regardless of switch loading
• Partitionable switch architecture 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 requiring deterministic latency
• Enterprise storage area networks (SANs)

Procurement Notes

This specific part number is classified as obsolete or end-of-life. Verification of availability requires checking distributor stock lists for remaining inventory or identifying qualified replacement components from the same product family. Ensure compatibility with existing PCB footprints and firmware configurations when sourcing alternatives.

Selection Notes

Select this component for applications requiring 64 PCIe Gen2 lanes with low latency and non-blocking performance. Verify that the design supports the 324-FCBGA package size and 3.3V power requirements. Consider partitioning capabilities if multi-root support is necessary for the target system topology.

Part Context

The 89H64H16AG2ZDBLI belongs to the IDT/Renesas 89PES series of PCIe Gen2 switches. It shares architectural similarities with models like the 89H64H16G2 but may differ in packaging or temperature grade suffixes. It is part of a lineage of high-port-count switches designed for enterprise and data center infrastructure.
