Introduction

The U31X4-PCIE8XE101 is an Quad channel 8-port (2-port x4) USB 3.1 to PCI Express x8 Gen 3 Host Card.

U31X4-PCIE8XE101 is integrated by the following three key parts (QIP2X-PCIE8XG301, DU31X2-IPCIE2XG322, CB-S0031).

  • QIP2X-PCIE8XG301
    • Internal Dual PCIe x4 (two SFF-8643 Connectors) to PCIe x8 Gen 3 Switch Host Card
  • DU31X2-IPCIE2XG322
    • Quad PCI Express to USB 3.1 Single Chip Host Controllers (Asmedia ASM3142, USB IF TID 5080000010).
  • Two CB-S0031
    • SFF-8643 to SFF-8643 Cable, L=50cm

Utilizing the standard PCI Express Switch, the 16-Lane/5-Port PCI Express Switch provides the most efficient fan-out solution for integrating Quad PCI Express to USB 3.1 Single Chip Host controllers into a small board design. Each USB 3.1 to PCI Express Single Chip Host controller takes advantages of 10 Gbps burst rate of 8-lane PCI Express bus in both directions and is fully compliant with PCI Express Base specification r3.0. This solution provides full PCI Express and USB 3.1 functionality and performance.
