89H24NT24G2ZCHLG

Overview

The 89H24NT24G2ZCHLG is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 lanes and 24 ports with non-blocking architecture for high-performance data transfer. The device operates at a maximum clock frequency of 125 MHz and supports data rates up to 192 Gb/s. Power supply requirements include 1 V, 2.5 V, and 3.3 V rails. It functions within an operating temperature range of -40°C to +85°C. The component is housed in a 324-FCBGA package with dimensions of 19x19 mm, designed for surface mount 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
• Features onboard DMA support and internal buffering optimized for large payloads

Applications

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

Procurement Notes

Verify the specific suffix ZCHLG against official Renesas documentation to confirm lead-free status and moisture sensitivity level. Confirm current availability as this series may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints for the 324-FCBGA package before procurement.

Selection Notes

Select this model when 24 ports of PCIe Gen2 connectivity are required. Compare against the 89H24NT6AG2 if fewer ports suffice. Verify that the 324-FCBGA package fits the design constraints. Check RoHS compliance requirements against the specific suffix designation.

Part Context

This part belongs to the 89H24NT24G2 family of PCIe switches from Renesas. It succeeds earlier IDT-branded components in the same category. The device integrates switching logic with flow control credits to maintain bandwidth efficiency under heavy load conditions.
