89H24NT24G2ZCHLGI

Overview

The 89H24NT24G2ZCHLGI is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 lanes and 24 ports, supporting data rates up to 192 Gb/s with a maximum clock frequency of 125 MHz. The device operates within an industrial temperature range of -40°C to +85°C and utilizes multiple supply voltages including 1 V, 2.5 V, and 3.3 V. It is housed in a 324-FCBGA package (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

Applications

• High-performance system interconnect switching
• Multi-root server architectures requiring partitionable switching
• Network infrastructure equipment demanding deterministic throughput

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 sensitivity. Ensure supply chain documentation matches the exact suffix ZCHLGI for correct temperature grade and lead-free specifications.

Selection Notes

Select this model when 24-port scalability and Gen2 lane density are required. Compare against the 89H24NT6AG2 series if fewer ports suffice but larger packages are acceptable. Verify voltage domain compatibility with target system rails. Consider the 324-FCBGA footprint constraints during PCB layout planning relative to thermal dissipation needs.

Part Context

This component belongs to the 89H24NT24G2 family of PCIe switches. It shares architectural similarities with other variants like the 89H24NT24G2ZAHLI and 89H24NT24G2ZBHLI8, differing primarily in packaging type, temperature rating, and lead-free status. The ZCHLGI suffix denotes specific commercial/industrial grade and tray/reel configuration details.

Replacement Considerations

Direct substitutes include 89H24NT24G2ZAHLI and 89H24NT24G2ZBHLI8. Verify pinout compatibility and electrical characteristics before substitution. Note that package variations may require mechanical re-evaluation of the host board design.
