Introduction

The U3X4-PCIE4XE306 is a Quad channel USB 3.0 (5Gbps) to PCI Express x4 Gen 2 Host Adapter.

U3X4-PCIE4XE306 is designed with the following two key components.

  • 8-Lane, 5-Port PCI Express Gen 2 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/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 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.

USB Bus Power Input

  • 12V Step-Down to 5V from either PCIe 12V or Power Connector 12V (ATA 4-pin or SATA 15-pin)

    The USB Bus power (5V) are step-down from 12V and the 12V input might from either PCIe Edge Connector or Auxiliary Power Connectors (J1 & J2).
    Note:
    If the PCIe Slot can’t supply 12V current high enough then you have to attach the Auxiliary Power from either J1 (ATA 4-pin) or J2 (SATA 15-pin).
