Details for USB 4 Version 2.0 have been released; expect up to 80 Gbps speeds

Thanks to the USB Promoter Group, the next-generation USB 4 Version 2.0 standards are now available. Data transmission speeds will significantly increase with the introduction of USB 4 Version 2.o, doubling them to 80 Gbps using USB Type-C cable and connection. Here are some further details.

USB 4. Version 2.0 Specs Revealed

By using 40 Gbps passive Type-C cables and 80 Gbps Type-C active cables, a novel physical layer architecture will be used to accomplish the 80 Gbps data transfer rates. Additionally, it will handle more recent data and display standards, and the bandwidth that is accessible has increased.

Support for USB 3.2 data tunnelling at speeds of up to 20 Gbps is provided via the data protocol. Additionally, the updated DisplayPort and PCIe requirements are supported. Support for USB 4 Version 1.0, USB 3.2, USB 2.0, and Thunderbolt 3 is also included in USB 4 Version 2.0.

“Once again following USB history, this new USB4 specification doubles data performance to bring higher levels of capability to the USB Type-C ecosystem,” said Brad Saunders, chairman of the USB Promoter Group. Higher-performance screens, storage, and USB-based hubs and ports are the solutions benefiting the most from this speed improvement.

The USB Promoter Group, which is made up of companies like Apple, Microsoft, Intel, and others, has also stated that it would update the USB Type-C and USB Power Delivery (USB PD) specifications soon. This will take place before the November USB DevDays developer gatherings.

Additionally, significant upgrades are coming for DisplayPort, PCI Express (PCIe) data tunnelling, and USB 3.2.

During the USB Developer Days in 2022, we anticipate learning additional specifics about the USB 4 2.0, USB Type-C, and USB PD standards. The event will take place in Seattle, Washington, on November 1-2, and Seoul, South Korea, on November 15–16. When this standard will be marketed is still up in the air!
