89H24NT24G2ZAHLG8

Overview

The 89H24NT24G2ZAHLG8 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 at 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
• Includes onboard DMA support and internal buffering with flow control credits

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Enterprise storage networking

Procurement Notes

Verify component authenticity and RoHS compliance status prior to integration. Confirm moisture sensitivity level handling procedures during assembly. Check for obsolescence notices or product change notifications from the manufacturer. Ensure compatibility with existing PCB footprint and power delivery networks. Validate lead-free status if required by specific environmental regulations.

Selection Notes

Select this component for designs requiring 24-port PCIe Gen2 connectivity with low latency. Consider the 324-FCBGA package constraints for layout planning. Evaluate thermal management needs given the operating temperature range. Compare against alternative lane counts if port density requirements differ. Verify voltage domain compatibility for all connected endpoints.

Part Context

This part belongs to the 89H24NT24G2 series of PCIe switches. It is functionally similar to variants like 89H24NT24G2ZCHLI8 but differs in packaging and manufacturing details. The series is designed for deterministic switching in complex system topologies. Other members include 89H24NT6AG2 and 89H32NT24AG2 with varying lane counts.

Replacement Considerations

Direct substitutes include 89H24NT24G2ZCHLI8 and IDT89H24NT24G2ZAHLI. Verify pinout compatibility and electrical parameters before substitution. Check for any functional differences due to package variations. Confirm availability and lifecycle status of potential replacement parts.
