3 Major Characteristics of the New USB 80Gbps Solution
- 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.
- 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.
- 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.
