Introduction

The U3X4-PCIE4XE313 is a Quad channel USB 3.0 to PCI Express x4 Gen 2 Host Adapter.

U3X4-PCIE4XE313 is designed with Two key components.

  • 8-Lane, 6-Port PCI Express Switch.
  • PCI Express to USB 3.0 Single Chip Host Controller (FRESCO FL1100, USB IF TID 380000026).

Utilizing the standard PCI Express Switch, the 8-Lane/6-Port PCI Express Switch provides the most efficient fan-out solution for integrating four 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 4-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.
