89HPES22H16ZABRI8

Overview

The 89HPES22H16ZABRI8 is a PCIe System Interconnect Switch providing 22 lanes and 16 ports. It features a non-blocking architecture optimized for high-performance system interconnect partitioning. The device supports true multi-root configurations through its partionable switch architecture. Internal buffering and flow control credits are utilized to maximize bandwidth and accommodate large payloads. This component delivers low latency and low power consumption while ensuring deterministic switching performance across all ports.

Feature Summary

• Provides 22 PCIe Gen1 lanes and 16 switch ports with full line rate, non-blocking throughput for multiple traffic flows regardless of switch loading.
• Features a partionable switch architecture designed to support true multi-root configurations within the system.
• Incorporates internal buffering and flow control credits optimized for maximum bandwidth and handling of large payloads.

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• I/O expansion systems

Procurement Notes

Verify the obsolete status and discontinuation notification prior to procurement. Confirm that the specific suffix ZABRI8 corresponds to the FCBGA-484 package with Industrial temperature grade and reel carrier type. Ensure compatibility with existing design requirements given the end-of-life status.

Selection Notes

Select this component when 22 PCIe Gen1 lanes and 16 ports are required for non-blocking switching. Consider the FCBGA-484 industrial grade package constraints. Evaluate alternative solutions if current production availability is critical due to the discontinued status.

Part Context

This part belongs to the 89HPES22H16 series of PCIe switches. It shares architectural similarities with other models in the family but is distinguished by its specific lane count, port configuration, and package variant. The series focuses on deterministic system interconnect switching capabilities.

Replacement Considerations

Public confirmed substitute part numbers are not available. The component is listed as obsolete. Designers should evaluate newer generations of PCIe switches or contact the manufacturer for potential last-time buy options.
