New USB4 Promises Faster Speed & Support

The USB Implementers Forum (USB-IF) has officially published new USB4 technical specifications, with the next wave of compatible devices tipped to launch as early as next year.

The update goes a long way in the delivery of next-gen USB architecture, which complements and builds upon the existing USB 3.2 and USB 2.0.

Based on Thunderbolt protocol specification, the USB4 architecture doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols.

Key characteristics include:

  • Two-lane operation using existing USB Type-C cables and up to 40Gbps operation over 40Gbps 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.

The upcoming USB Developer Days 2019 will include detailed technical training covering the USB4 specification and the latest for USB Type-C, USB Power Delivery, and new USB-IF branding strategies.

Registration information for the following opportunities are available on the USB-IF website.
