89H24NT24G2ZAHLI8

Overview

The 89H24NT24G2ZAHLI8 is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 lanes and 24 ports of high-performance, deterministic switching with non-blocking architecture. The device supports multiple traffic flows at full line rate regardless of switch loading. It operates within a temperature range of -40°C to +85°C and utilizes a 324-FCBGA package. Electrical specifications include a maximum clock frequency of 125 MHz and data rates up to 192 Gb/s. Power supply requirements are specified as 1 V, 2.5 V, and 3.3 V.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect partitioning
• Supports true multi-root configurations through partitionable switch architecture
• Enables movable upstream support and on-board DMA capabilities
• Features internal buffering and flow control credits optimized for large payloads

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• PCIe I/O expansion systems

Procurement Notes

Verify component authenticity and RoHS compliance status prior to integration. Confirm moisture sensitivity level handling procedures during storage and assembly. Ensure compatibility with existing power delivery networks for the required voltage rails. Validate package dimensions against PCB footprint specifications to prevent mechanical interference.

Selection Notes

Select this component for applications requiring deterministic latency and high bandwidth across multiple PCIe Gen2 links. Consider the 324-FCBGA package constraints during thermal management design. Evaluate the need for Nontransparent Bridging functions if isolating root complexes is required. Verify that the 24-port configuration aligns with system topology requirements.
