89H24NT24G2ZAHL8

Overview

The 89H24NT24G2ZAHL8 is a PCI Express Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 PCIe lanes and 24 ports, supporting data rates up to 192 Gb/s with a maximum clock frequency of 125 MHz. The device operates within a temperature range of -40°C to +85°C and utilizes a 324-FCBGA package. Power requirements include supply voltages of 1 V, 2.5 V, and 3.3 V. It features a 32/64-bit data bus width and supports SMD/SMT installation.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support capabilities
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• I/O expansion systems requiring peer-to-peer data transfers

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance requirements as the specific variant may not meet current environmental standards. Validate package integrity upon receipt given the FCBGA form factor. Ensure storage conditions adhere to moisture sensitivity level specifications to prevent damage during assembly processes.

Selection Notes

Select this component when 24-port PCIe Gen2 connectivity is required for deterministic switching performance. Consider the 324-FCBGA footprint constraints during PCB layout design. Evaluate power delivery networks for the 1 V, 2.5 V, and 3.3 V rails. Verify thermal management solutions for operation within the specified industrial temperature range.

Part Context

This part belongs to the 89H24NT24G2 series of PCIe switches from Renesas. It shares architectural similarities with other models in the family but differs in pinout and packaging options. The ZAHL8 suffix indicates specific packaging and material configurations distinct from other variants like ZBHLI8 or ZCHLI8.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Compatible alternatives within the same product family should be evaluated based on lane count and port configuration compatibility.
