89H24NT24G2ZCHLGI8

Overview

The Renesas 89H24NT24G2ZCHLGI8 is a PCI Express Gen2 system interconnect switch providing 24 lanes and 6 ports. It operates with a maximum clock frequency of 125 MHz and supports data rates up to 192 Gb/s. The device utilizes a 324-FCBGA package (19x19 mm) with surface mount installation. Power requirements include supply voltages of 1 V, 2.5 V, and 3.3 V. It functions within an operating temperature range of -40°C to +85°C and features a 32/64-bit data bus width.

Feature Summary

• Supports partitionable switch architecture for multi-root systems
• Enables dynamic port reconfiguration across exchange partitions
• Integrates multiple Nontransparent Bridging (NTB) functions

Applications

• High-performance server system interconnects
• Storage area network infrastructure
• Communication equipment switching
• Embedded systems requiring PCIe expansion

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 to ensure suitability for automated surface mount assembly processes.

Selection Notes

Select this model when 24 lanes and 6 ports are required for non-blocking PCIe Gen2 traffic. Ensure design compatibility with 1V, 2.5V, and 3.3V power domains. Verify that the 324-FCBGA footprint fits the target PCB layout constraints.

Part Context

This component belongs to the IDT/Renesas 89H series of PCIe switches. It shares architectural similarities with models like the 89H24NT6AG2 but offers higher port density. The suffix ZCHLGI8 indicates specific packaging and lead-free characteristics within the product family.

Replacement Considerations

Direct substitutes include other variants in the 89H24NT24G2 series such as 89H24NT24G2ZBHLI8 or 89H24NT24G2ZAHLI, provided pinout and electrical specifications match the original design requirements.
