89H34H16G2ZCBLI

Overview

The 89H34H16G2ZCBLI is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 34 lanes and 16 ports with non-blocking architecture for high-performance deterministic switching. The device supports partitionable switch architecture for multi-root support, internal buffering, and flow control credits optimized for maximum bandwidth and large payloads. It operates at a maximum clock frequency of 125 MHz with power supply voltages of 1 V, 2.5 V, and 3.3 V. The component functions within an operating temperature range of -40°C to +85°C and utilizes a 1156-lead FCBGA package.

Feature Summary

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

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Storage area networks requiring deterministic latency

Procurement Notes

Verify the specific suffix ZCBLI against official Renesas documentation to confirm lead-free status and moisture sensitivity level. Confirm end-of-life status and availability through authorized distributors as this component may be obsolete or restricted in certain regions.

Selection Notes

Select this model when 34 lanes and 16 ports are required for PCIe Gen2 applications. Ensure the design accommodates the 1156-lead FCBGA package dimensions and thermal requirements. Verify compatibility with 1 V, 2.5 V, and 3.3 V power domains during board layout.

Part Context

This part belongs to the 89H series of PCIe switches from Renesas (formerly IDT). It shares architectural similarities with other models like the 89H64H16G2 but offers a specific lane-to-port ratio suited for mid-range system interconnect needs. The ZCBLI suffix indicates specific packaging and environmental compliance details.
