Introduction

The U3X8-PCIE8XE104 is Octad channel 8-port (1-port x 8) USB 3.0 to PCI Express x8 Gen 2 Host Adapter.

U3X8-PCIE8XE104 is designed with Two key components.

  • 16-Lane, 16-Port PCI Express Switch.
  • PCI Express to USB 3.0 Single Chip Host Controller (Renesas uPD720202; USB IF TID 380000043).

Utilizing the standard PCI Express Switch, the 16-Lane/16-Port PCI Express Switch provides the most efficient fan-out solution for integrating Eight PCI Express to USB 3.0 Single Chip Host controllers into a small board design. Each USB 3.0 to PCI Express Single Chip Host controller takes advantages of 5 Gbps burst rate of 8-lane PCI Express bus in both directions and is fully compliant with PCI Express Base specification r2.0. This solution provides full PCI Express and USB 3.0 functionality and performance.

The design supports Per Port Power Switching and Over-Current Notification. The 2.0A (70mΩ on-resistance) Single Channel Current-Limited Power Switch (UL File Number E322375) has fast short-circuit Response time for improved overall system robustness, and have integrated output discharge function to ensure completely controlled discharging of the output voltage capacitor. They provide a complete protection solution for applications subject to heavy capacitive loads and the prospect of short circuit, and offer reverse current blocking, over-current, over-temperature and short-circuit protection, as well as controlled rise time and under-voltage lockout functionality.
