• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream capabilities
• Includes on-board DMA support with internal buffering and flow control credits

Applications

• High-performance computing system interconnects
• Multi-root support architectures requiring deterministic switching
• Industrial control systems requiring low latency and low power consumption

Procurement Notes

Verify the exact suffix configuration when sourcing replacements, as variations such as ZCHLGI8 or ZCHLG may indicate different packaging or temperature grades. Confirm current availability status, as this specific part number may be discontinued or subject to long-lead times. Ensure that the selected substitute maintains the same FCBGA footprint and voltage specifications to guarantee mechanical and electrical compatibility in existing designs.

Selection Notes

Select this component for applications requiring a dense PCIe Gen2 switch solution with multi-root support capabilities. Consider the 324-FCBGA package size during PCB layout planning to ensure adequate thermal dissipation and signal integrity. Evaluate the need for Nontransparent Bridging functions if connecting disparate system domains. Verify that the design supports the required 1 V, 2.5 V, and 3.3 V power rails for proper operation across all port configurations.

Part Context

This device belongs to the 89H12N series of PCIe switches, which are engineered for scalable and flexible system interconnect solutions. The series typically includes variants with different pin counts and lane configurations to suit diverse networking and storage applications. The 89H12NT12G2ZAHLI specifically targets the mid-range segment, offering a balance between port density and power efficiency for enterprise and industrial environments.

Replacement Considerations

Publicly confirmed substitutes include the 89H12NT12G2ZCHLG and 89H12NT12G2ZCHLGI8. These alternatives share the same core functionality and package type but may differ in packaging format or specific qualification grades. Verify pin-to-pin compatibility before implementation.
