89H24NT24G2ZCHLG8

Overview

The 89H24NT24G2ZCHLG8 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 ambient temperature range of -40°C to +85°C and utilizes a 324-FCBGA package (19x19 mm). 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
• Partitionable switch architecture enabling true multi-root support
• Supports multiple Nontransparent Bridging (NTB) functions

Applications

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

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, as moisture sensitivity level 4 requires strict handling protocols during storage and assembly processes.

Selection Notes

Select this component when 24-port PCIe Gen2 connectivity is required for non-blocking throughput. Ensure design compatibility with 1 V, 2.5 V, and 3.3 V power domains. Verify that the 324-FCBGA footprint fits the target PCB layout constraints. Consider thermal management solutions suitable for the industrial temperature range if operating near upper limits.

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 pin count and port configuration. The ZCHLG8 suffix indicates specific packaging and material characteristics distinct from tray-packaged or lead-free variants within the same functional group.
