89H24NT6AG2ZCHLI

Overview

The 89H24NT6AG2ZCHLI is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 lanes and 6 ports of high-performance, deterministic switching with non-blocking architecture. The device supports up to 192 Gb/s data rate and operates at a maximum clock frequency of 125 MHz. It utilizes an FCBGA-484 package (23x23 mm) for surface mount installation. Electrical specifications include supply voltages of 1 V, 2.5 V, and 3.3 V. The component functions within a temperature range of -40°C to +85°C and features a 32/64-bit data bus width.

Feature Summary

• Supports partitionable switch architecture enabling true multi-root support through multiple independent switching domains.
• Integrates Nontransparent Bridging (NTB) functions allowing communication between switch partitions and external PCIe domains.
• Features movable upstream support and on-board DMA capabilities for flexible system topology and bandwidth optimization.

Applications

• High-performance server system interconnects requiring multi-root I/O virtualization.
• Storage area networks needing deterministic low-latency data transfer paths.
• Communication infrastructure equipment utilizing peer-to-peer switching architectures.

Procurement Notes

Verify the specific suffix ZCHLI against official Renesas documentation to confirm lead-free status and industrial temperature grade. Confirm end-of-life status as this model family has been discontinued. Source replacement components from authorized distributors only to ensure authenticity and compatibility with existing PCB footprints.

Selection Notes

Select this component when designing systems requiring 24 lanes of PCIe Gen2 connectivity with partitionable switching capabilities. Ensure the design accommodates the FCBGA-484 package dimensions and thermal requirements. Verify that the host platform supports the necessary voltage rails and signal integrity standards for 5.0 GT/s operation.

Part Context

This part belongs to the IDT 89HPES24NT6A series, which was acquired by Renesas Electronics. It serves as a successor to earlier PCIe switching solutions, offering enhanced partitioning and NTB features compared to standard switches. The device is designed for complex enterprise environments where isolated switching domains are required.

Replacement Considerations

Public records indicate the 89H24NT6AG2ZCHLGI variant shares the same core functionality but differs in moisture sensitivity level and lead-free compliance. No other direct pin-compatible replacements are confirmed in public datasheets for this specific discontinued model.
