The xHCI host controller allows interfacing with USB 2.0 and USB 3.2.
Integrating ASMedia’s self-designed physical layers (PHYs), this controller is implemented with USB4 router including the time measurement unit (TMU) and several PCIe downstream/DisplayPort IN/USB downstream adapters, PCI Express switch, DisplayPort retimer and Intel® eXtensible Host Controller Interface. This controller is in compliance with USB4 Specification Rev 1.0, VESA DisplayPort Standard V1.4a, VESA DisplayPort Alt Mode on USB Type-C Standard V2.0, and PCI Express Base Specification Rev 4.0 V1.0. This controller also supports multiple protocol tunneling and USB 3.2 and DisplayPort alternate mode, providing high bandwidth up to USB4 Gen 3x2 40Gbps, USB 3.2 SuperSpeedPlus Gen 2x2 20Gbps and DisplayPort HBR3 x4 up to 32.4Gbps. It features upstream ports with 4-lane PCI Express 4.0 (PCIe Gen 4) and dual 4-lane DisplayPort sink ports, and downstream facing ports with dual USB4 ports.
