89H24NT24G2ZCHL8

Overview

The 89H24NT24G2ZCHL8 is a PCI Express Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 PCIe lanes and 24 ports for high-performance, deterministic switching. The device supports a maximum clock frequency of 125 MHz with a data rate of 192 Gb/s. It operates on supply voltages of 1 V, 2.5 V, and 3.3 V. The component functions within an operating temperature range of -40°C to +85°C. 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
• I/O expansion systems requiring non-blocking throughput

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance requirements as the part is marked non-compliant. Validate package integrity upon receipt given the FCBGA form factor. Check for specific manufacturing date codes relevant to project timelines. Ensure proper handling procedures are followed for moisture-sensitive devices.

Selection Notes

Select this component when 24-port PCIe Gen2 connectivity is required. Ensure design compatibility with 1V, 2.5V, and 3.3V power domains. Verify PCB layout supports the 324-FCBGA footprint dimensions. Consider thermal management solutions for the specified industrial temperature range. Evaluate alternative packages if different pin counts or lead-free requirements exist.

Part Context

This part belongs to the 89H24NT24G2 series of PCIe switches. It shares architectural similarities with other models in the family but differs in packaging and specific suffix designations. The ZCHL8 suffix indicates specific material and packaging configurations distinct from tray-based variants. It serves as a specialized interface IC for complex switching topologies.

Replacement Considerations

Direct substitutes include IDT89H24NT24G2ZCHLI8. Verify functional equivalence regarding lane count and port configuration. Confirm package compatibility before substitution. Review datasheet revisions for any parameter deviations between original and replacement parts.
