The USB Promoter Group has released the specifications for the next-generation USB 4 Version 2.0. It has been shown that USB 4 Version 2.0 will double the speed of data transfer to 80 Gbps over a USB Type-C cable and connector. This is a big change. Here are some more details.
With a new physical layer architecture and 40 Gbps passive Type-C cables and 80 Gbps active Type-C cables, the 80 Gbps data transfer speeds will be reached. It will also work with new data and display protocols, and the available bandwidth will be bigger.
The data protocol lets USB 3.2 data tunneling work at speeds of up to 20 Gbps. There is also support for DisplayPort and PCIe specs that have been updated. USB 4 Version 2.0 also works with USB4 Version 1.0, USB 3.2, USB 2.0, and Thunderbolt 3.
Brad Saunders, Chairman of the USB Promoter Group, said, “In keeping with USB tradition, this updated USB4 specification doubles data performance to give the USB Type-C ecosystem more ways to work. The solutions that will benefit the most from this speed boost are those with better displays, storage, and USB hubs and docks.
The USB Promoter Group, which includes Apple, Microsoft, Intel, and others, has also confirmed that the USB Type-C and USB Power Delivery (USB PD) specifications will be updated soon. This will happen before the November USB DevDays developer events.
A lot of changes are also coming to USB 3.2, DisplayPort, and PCI Express (PCIe) data tunneling.
During the USB Developer Days 2022, we hope to learn more about the specs for USB 4 2.0, USB Type-C, and USB PD. The event will take place in Seattle, Washington, on November 1 and 2, and in Seoul, South Korea, on November 15 and 16. It’s still not clear when this standard will be available for sale.
