3 Major Characteristics of the New USB 80Gbps Solution

  1. The solution offers up to 80Gbps transfers through the utilization of a new physical layer architecture based on PAM3 signal encoding, USB Type-C passive cables, and USB Type-C active cables.
    • Optionally for certain applications, such as driving high-performance USB4-based displays, the USB Type-C signal interface can be configured asymmetrically to deliver up to 120Gbps in one direction while retaining 40Gbps in the other direction.
  2. The solution offers updates to data and display protocols for better use of the increase in available bandwidth.
    • USB data architecture updates now enable Enhanced SuperSpeed USB data tunneling to exceed 20Gbps.
    • Aligns with DisplayPort™ Revision 2.1 and PCI Express® Revision 4.
  3. Backward compatibility with all previous versions of USB.

Guidelines for identifying certified USB 80Gbps solutions and cables will follow the new unified USB-IF branding and marketing program. As a reminder, USB specification names and technical terminology are not intended for use when describing USB capabilities to end consumers.
