1. Host USB 3.2 data transmission path: As shown by the red line in the figure, when the enhanced super-speed host transmits data, there are two USB3 downstream port adapters. A single transmission is sele-cted through one of them, and then transmitted to one of the two USB4 ports. Finally, USB 3.2 data is transmitted through the USB Type-C port.
2. Host USB 2.0 data transmission path: As shown by the yellow line in the figure, the USB 2.0 host sends and receives USB 2.0 data directly through the USB Type-C port.
3. Host PCIe data transmission path: As shown by the green line in the figure, when transmitting PCIe data, the PCIe controller selects one of the two PCIe downstream port adapters to transmit the data, and then passes the PCIe data to one of the USB4 ports, and then Passed to the USB Type-C port.
4. Host DisplayPort transmission path: As shown by the purple line in the figure, the DisplayPort transmission source transmits the video signal to the DisplayPort adapter, then to one or two USB4 ports, and finally sends it through the USB Type-C port connected to the USB4 port. output video signal.
