Fundamentals of USB4 Architecture Course Details:

The addition of USB4 introduces an entirely new capability--interleaved USB 3.2, PCI Express (PCIe), and DisplayPort (DP) packets on the multi-protocol USB4 link. One of the most important use cases for multiplexed IO protocols over a single bus applies to laptops, notebooks, tablets, and other small form factors where space is limited for both internal peripherals and external IO connectors. In this scenario, a USB4 dock may be connected to the host; downstream of the dock may be native protocol PCIe, USB 3.2, and DisplayPort peripherals: SSD, GPU, LAN adapter, multiple displays, etc. If a dock isn’t needed, a USB4 port can be dedicated to a high bandwidth peripheral or charging power.

USB4 employs an enhanced version of Intel’s Thunderbolt 3 packet tunneling scheme to support multiple protocols on a physical interface based on USB-C defined connectors, cables, and power delivery (USB PD). The USB-C connection used by USB4 also supports the backward compatibility required if native USB 3.x, USB 2.0, or DisplayPort alternate mode devices are attached to USB4-capable USB-C ports.

This MindShare Fundamentals course presents a high-level overview of the USB4 architecture, including hosts, hubs, and peripherals as well as link traffic and the role of the USB4 connection manager.

You Will Learn:

  • USB4 motivations and goals
  • Host, hub, peripheral device architecture
  • USB4 link and its USB-C receptacles/cables
  • The layered USB4 protocol
  • USB4 host interface and connection manager role
  • Tunneled and control packets
  • Role of USB4 configuration spaces
