Introduction

The U3X4-PCIE1XE110 is a Quad channel USB 3.0 to PCI Express Gen 2 Host Adapter.

U3X4-PCIE1XE110 is designed with Two key components.

  • 5-Lane, 5-Port PCI Express Switch.
  • PCI Express to USB 3.0 Single Chip Host Controller.

Utilizing the standard PCI Express Switch, the 5-Lane/5-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 2.5 Gbps burst rate of 1-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.
