PCIe X4 USB 3 Card: A High-Speed Connectivity Solution

The U31X2-PCIE4XG321 is a dual-channel, four-port USB 3.2 Gen 2 to PCIe x4 host adapter that offers high-speed connectivity and performance for various applications. This card complies with the PCI Express Electromechanical specification 2.0 and the PCI Express Base specification r3.0, ensuring compatibility with a wide range of systems.

With its advanced design, this card takes advantage of the 10 Gbps burst rate of the four-lane PCIe bus in both directions, providing fast data transfer rates and low latency. The weighted round-robin source port arbitration feature ensures efficient resource allocation, while the link power management states (L0, L0s, L1, L2/Ready) help to reduce power consumption.

The U31X2-PCIE4XG321 is equipped with two independent USB 3.2 host controllers, each supporting four USB 3 cable ports (Type-C receptacles). The card complies with Intel's eXtensible Host Controller Interface (xHCI) specification Revision 1.1 and the Universal Serial Bus 3.2 Specification Revision 1.0.

The primary PCIe function of this card provides full PCI Express and USB 3.2 functionality, with a maximum bandwidth performance of up to 10 Gbps. The 12-lane, five-port PCIe Gen 3 switch enables efficient fan-out solutions for integrating multiple USB 3.2 Gen 2 single chip host controllers into a small board design.

The U31X2-PCIE4XG321 is designed with two key components: the PCI Express to USB 3.2 Single Chip Host Controller (Asmedia ASM3142, USB IF TID 5080000010) and the 12-Lane, 5-Port PCIe Gen 3 Switch. This card provides a USB 3.x cable port lock mechanism, ensuring secure connections between devices.

In summary, the U31X2-PCIE4XG321 is a high-speed connectivity solution that offers advanced features and performance for various applications. Its compatibility with multiple standards and specifications makes it an ideal choice for systems requiring fast data transfer rates and low latency.
