Introduction

The U3X4-PCIE4XE101 is a Quad channel USB 3.0 to PCI Express x4 Gen 2 Host Adapter.

U3X4-PCIE4XE101 is designed with Two key components.

  • 8-Lane, 8-Port PCI Express Switch.
  • PCI Express to USB 3.0 Single Chip Host Controller (Renesas uPD720202; USB IF TID 380000043).

Utilizing the standard PCI Express Switch, the 8-Lane/8-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.

Number of Ports

Four independent USB 3.0 Cable Ports
(A-type Receptacle)

USB Bus Power Input

5V from either ATA 4-pin Power Connector (J1)
or/and SATA 15pin Power Connector (J2)
Computer Platform

Computer with PCI Express slot ( x4, x8, x16)

Note:
For the best performance (5.0 Gbps), It should be installed in a PCIe Gen 2 compliant slot in the host computer.  Most computers have PCIe Gen 2 (5.0 Gbps) throughput on x8 or x16 slots.
A PCIe Gen 1 compliant slot reaches up to 2.5 Gbps throughput
