The USB Promoter Group has announce that USB 4 version 2.0 will support data transfer speeds of up to 80Gbps over the USB Type-C cable and connector. This organisation also said that USB Type-C and USB Power Delivery (USB PD) specifications will also be update to reach the claim performance.
The USB 4 Version 2.0 will also feature backwards compatibility with the previous USB 4 version.
More details of the USB 4 Version 2.0 specification are expect to be reveale ahead of the USB Developer Days 2022 event that will take place in November, as per the group.
In a press release, the USB Promoter Group, which is comprise of Apple, HP, Intel, Microsoft, Renesas Electronics, STMicroelectronics, and Texas Instruments, announce that the USB 4 version 2.0 will allow data transfer of speeds up to 80Gbps over the USB Type-C cable and connector.
The group said that the USB Type-C and USB PD specifications will also be upgrade to support the higher data transfer speeds.
The USB 4 version 2.0 is base on a new physical layer architecture, which uses the existing 40Gbps USB Type-C passive cables and “newly-defined” USB Type-C active cables, as per the USB Promoter Group.
The organisation is also working on protocol updates to allow USB 3.2 data tunnelling to exceed speeds of 20Gbps, and to enable better alignment with the latest versions of DisplayPort and PCle data tunnelling.
The USB 4 Version 1.0, USB 3.2, USB 2.0, and ThunderBolt 3 will be compatible with the USB 4 version 2.0.
This USB Promoter Group also said that additional specifications of the new version of USB 4 are expect to be shared ahead of the USB Developer Days 2022 event in November.
The event will also provide technical training covering the new updates to USB 4, USB Type-C, and USB PD, as per group.
Joe Balich, a spokesperson for the USB Implementers Forum (USB-IF) told, that a USB 4 cable, which is rate 40Gbps, would be able to achieve twice its current data transfer speed in the future, when the next version of USB 4 is available.
