The USB 3.2 era is coming: Type-A interface will be completely abandoned

Under the use of USB3.1 Gen2, the specification of USB 3,2 Gen 2 was announced at the end of September 2017

• USB 3.2 Gen 1x1 - SuperSpeed, 5 Gbit/s (0.625 GB/s) data signaling rate over 1 lane using 8b/10b encoding, the same as USB 3.1 Gen 1 and USB 3.0.

• USB 3.2 Gen 1x2 - SuperSpeed+, new 10 Gbit/s (1.25 GB/s) data rate over 2 lanes using 8b/10b encoding.

• USB 3.2 Gen 2x1 - SuperSpeed+, 10 Gbit/s (1.25 GB/s) data rate over 1 lane using 128b/132b encoding, the same as USB 3.1 Gen 2.

• USB 3.2 Gen 2x2 - SuperSpeed+, new 20 Gbit/s (2.5 GB/s) data rate over 2 lanes using 128b/132b encoding.

In May 2018, Synopsys demonstrated the first USB 3.2 connection, where a Windows PC was connected to a storage device, reaching a speed of 1.6 GB/s average.

USB 3.2 is supported with the default Windows 10 USB drivers and in Linux Kernel

Synopsys publicly demonstrated USB 3.2 for the first time.

The USB 3.2 that Synopsys demonstrated this time is based on the HAPS-80 FPGA hardware prototype platform, with a single-channel bandwidth of 10Gbps, and a dual-channel can reach the 20Gbps required by USB 3.2. The HAPS platform connects to the PC via PCI-E and serves as a large-capacity storage device.

In this demonstration, USB 3.2 ran out of 1.6GB/s, which has not yet reached the highest value of the standard, and has potential; in addition, it is worth mentioning that USB 3.2 will use Type-C interface, which is still The popular Type-A interface will be completely abandoned in the USB 3.2 era.
