Introduction

The U3X8-EP8XE102E is an Octad channel 8-port (1-port x 8) USB 3.0 to External PCI Express x8 Gen 2 Host Docking

U3X8-EP8XE102E is integrated by the following three key parts (DEP4X-PCIE8XG201, U3X8-EP8XG201E, CB-00485).

  • DEP4X-PCIE8XG201---Dual External PCIe x4 (with PCIe to PCIe Packet Switch) to PCI Express x8 Cable Adapter
    • Upstream: 8-lane PCI Express
    • Downstream: Eight 1-lane PCI Express
  • U3X8-EP8XG201E---Eight channel 8-port (1-port x 8) USB 3.0 to PCI Express x8 Gen 2 Docking
    • Integrated Eight Independent USB 3.0 to PCI Express x1 Gen 2 Host Controllers
    • Each Channel USB 3.0 has one Cable Port
