USB4 Release With Support Upto 40 Gbps Data Transfer

The USB Implementer Forum (USB-IF) announced the USB4 spec recently. The new spec uses cables that offers up to dual-lane 40Gbps speed over 40 Gbps-certified cables.

“Releasing the Thunderbolt protocol specification is a significant milestone for making today’s simplest and most versatile port available to everyone,” said Jason Ziller, general manager of Intel’s Client Connectivity Division.

It supports multiple data and display protocols along with backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3. The USB4 architecture incorporates the Thunderbolt 3 technologies.

Intel’s Thunderbolt 3 technology has a single port that supports multiple standards like Thunderbolt, USB 3.1, DisplayPort. The predecessors, USB 3.2 2×2 specification can only transfer data up to 20 Gbps. The speed of Thunderbolt 3 is 40Gbps which is twice that of Thunderbolt 2.

The new interface has a native support for video output over USB and also uses the same Type-C connector. The USB power delivery is up to 100W system charging.

“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.” Organization further added

We can expect the first computers, tablets, phones, and other devices the supports USB4 specs in a couple of months.
