Introducing USB4

Aug. 31, 2021
USB4 products should be showing up soon now that the chips have arrived.

This is part of Electronic Design's TechXchange Talks series.

Editor Bill Wong talks with USB Implementers Forum (USB-IF) president, Jeffrey Ravencraft, about the imminent flood of USB4 products that can handle dual hi-res displays with a single cable. The standard was released in 2019.

Key features of USB4 include:

  • Two-lane operation using existing USB Type-C cables
  • Speeds up to 40-Gb/s operation over 40-Gb/s certified cables
  • Multiple data and display protocols that efficiently share the maximum aggregate bandwidth
  • Backward compatibility with USB 3.2, USB 2.0, and Thunderbolt 3
