89H16NT16G2ZCHLG

Overview

The 89H16NT16G2ZCHLG is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, functioning as a PCI Express system interconnect switch. It provides 16 PCIe Gen2 lanes and 16 ports for high-performance, deterministic switching. The device operates on a 3.3V supply voltage and utilizes a 324-FCBGA package with dimensions of 19x19 mm. It supports surface mount installation and offers non-blocking throughput across all ports regardless of switch loading.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partionable 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 requiring partitionable switching
• Network infrastructure equipment utilizing Nontransparent Bridging

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance variations between manufacturing lots. Validate package integrity upon receipt as the component is moisture sensitive. Check for specific ordering suffixes that may indicate lead-free or industrial temperature grade variants. Ensure compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when 16-port PCIe Gen2 switching is required within a compact FCBGA form factor. Consider the 3.3V power requirement and thermal characteristics for board layout. Evaluate the need for Nontransparent Bridging features versus standard switching operations. Verify that the 19x19 mm package dimensions fit the target enclosure constraints.

Part Context

This part belongs to the 89HPES16NT16G2 family of PCI Express switches originally developed by Integrated Device Technology (IDT), now part of Renesas Electronics. The series includes various packaging and environmental option suffixes. It serves as a legacy solution for Gen2 interconnect needs in enterprise and storage systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The component is listed as obsolete. Designers should consult Renesas for current portfolio alternatives or evaluate pin-compatible successors from other manufacturers if migration is necessary.
