89H24NT24G2ZAHL

Overview

The Renesas 89H24NT24G2ZAHL is a PCI Express Gen2 switch interface IC designed for high-performance system interconnect applications. It provides 24 PCIe lanes and 24 ports, supporting a maximum clock frequency of 125 MHz with a data rate of 192 Gb/s. The device operates on supply voltages of 1 V, 2.5 V, and 3.3 V. It features a 32/64-bit data bus width and is housed in a 324-FCBGA package (19x19 mm) suitable for surface mount installation. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports non-blocking switching architecture optimized for high-performance system interconnect partitioning.
• Enables true multi-root support through partitionable switch architecture capabilities.
• Integrates multiple Nontransparent Bridging (NTB) functions for complex network topologies.

Applications

• High-performance server system interconnect switching
• Multi-root storage area network configurations
• Enterprise infrastructure networking equipment

Procurement Notes

Verify the exact suffix designation when sourcing, as variants like ZBHLI8 or ZCHLI8 exist with different packaging or lead-free statuses. Confirm current availability status directly with authorized distributors, as this specific part number may be subject to limited stock or end-of-life restrictions. Ensure compatibility with existing PCB layouts requiring the 324-FCBGA footprint before procurement.

Selection Notes

Select this model when a 24-lane, 24-port PCIe Gen2 solution is required for deterministic switching. Compare against the 89H24NT6AG2 series if fewer ports are needed but a larger package is acceptable. Verify that the 1V, 2.5V, and 3.3V power requirements align with the target system's power delivery design. Check moisture sensitivity level (MSL 4) constraints during assembly planning.

Part Context

This component belongs to the IDT 89H24NT24G2 family of PCIe switches, originally developed by Integrated Device Technology before its acquisition by Renesas Electronics. It serves as a bridge between host processors and peripheral devices in demanding computing environments. The 'ZAHL' suffix typically denotes specific packaging and environmental compliance attributes within this product line.

Replacement Considerations

Direct pin-to-pin replacements are not explicitly listed in public documentation for this exact suffix. Consider the 89HPES24T3G2ZCAL8 or 89HPES24T6G2ZCAL for similar port counts but verify package and feature differences carefully. Cross-reference with the broader 89H24NT6AG2 family for architectural similarities, though pinouts may differ.
