Introduction

The U3X4-EP4XE112E is an Quad channel 16-port (4-port x 4) USB 3.0 to External PCI Express x4 Gen 2 Host Docking

U3X4-EP4XE112E is integrated by the following four key parts (EP4X-PCIE4XG201, U3X4-EP4XG211E, CB-00485).

  • EP4X-PCIE4XG201 --- PCIe Cable Adapter (with PCIe to PCIe Packet Switch)
    • Upstream: 4-lane PCI Express
    • Downstream: Four 1-lane PCI Express
  • U3X4-EP4XG211E---Quad channel 16-port (4-port x 4) USB 3.0 to PCI Express x4 Gen 2 Docking
    • Integrated Quad Independent USB 3.0 to PCI Express x1 Gen 2 Host Controllers
    • Each Channel USB 3.0 has Four Cable Ports
  • CB-00485
    • External PCIe x4 Cable

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