Today the USB Promoter Group has today announced USB 4 specifications revealing details of the planned major update to deliver the next generation USB architecture that compliments and builds on the existing USB 3.2 and USB 2.0 architectures.
The USB 4 architecture is based on the Thunderbolt protocol specification recently contributed by Intel Corporation, doubling thebandwidth of USB and enabling multiple simultaneous data and display protocols.
“The primary goal of USB is to deliver the best user experience combining data, display and power delivery over a user-friendly and robust cable and connector solution,” said Brad Saunders, USB Promoter Group Chairman. “The USB4 solution specifically tailors bus operation to further enhance this experience by optimizing the blend of data and display over a single connection and enabling the further doubling of performance.” Key characteristics of the USB4 solution include:
– Two-lane operation using existing USB Type-C cables and up to 40 Gbps operation over 40 Gbps certified cables
– Multiple data and display protocols to efficiently share the total available bandwidth over the bus
– Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3
“The new USB4 architecture defines a method to share a single high-speed link with multiple end device types dynamically that best serves the transfer of data by type and application. As the USB Type-C connector has evolved into the role as the external display port of many host products, the USB4 specification provides the host the ability to optimally scale allocations for display data flow. Even as the USB4 specification introduces a new underlying protocol, compatibility with existing USB 3.2, USB 2.0 and Thunderbolt 3 hosts and devices is supported; the resulting connection scales to the best mutual capability of the devices being connected. “
