USB 3.2 Promises "Double Speed" With Same Cable

USB 3.2 Specification Promises “Double Speed” Using The Same Type-C Connector

USB 3.2 Promises “Double Speed” With Same Cable

The existing SuperSpeed USB physical layer data rates and encoding techniques will also go along with the new USB specification. Of course, a new USB 3.2 host must be used with a new USB 3.2 device and the appropriate certified USB Type-C cable to enjoy the headline speed and bandwidth advances. Amidst all this, the USB 3.0 Promoter Group has unveiled USB 3.2 adding to the confusion. The USB 3.2 update delivers the next level of performance.

USB is getting much faster yet again. In short, that means that upcoming devices should be able to transfer data more quickly than current ones.

The USB 3.0 Promoter Group - which includes Microsoft, Apple, Intel, HP, and others - has announced the USB 3.2 specification. While USB host controllers were initially designed for single-lane operation, the USB 3.2 spec doubles that to two, allowing for two 5 Gbps lanes (which would equal the 10Gbps maximum of the current spec) or two 10 Gbps lanes, boosting maximum throughput to 20 Gbps. Hopefully, we will hear more about it at USB Developer Days event in September. USB 3.2 enables the design of hosts and devices with multi-lane solutions, with up to two lanes of 5Gbps or 10Gbps operation, "effectively doubling the performance across existing cables", the group said. Although being used for single-lane operation as of now, the Group said that the Type-C already have support for the multi-lane operation.

Inflation subdued in the June quarter
In the Q&A session he also acknowledged that if wages growth averages only 2%, "we won't get back to 2.5% inflation". Mr Rudings said, however, the main event for markets will be the statement from the US Federal Reserve overnight.

Just like every USB version, USB 3.2 interface will be backward compatible with previous generations.

This update will, however, require new hardware on either end of that cable. Cables now qualified for USB 3.1 generation 1's 5 Gbps will be able to operate at 10 Gbps; those qualified for generation 2's 10 Gbps will be able to run at 20 Gbps. For example, a USB 3.2 host connected to a USB 3.2 storage device will now be capable of realizing over 2 GB/sec data transfer performance over an existing USB Type-C™ cable that is certified for SuperSpeed USB 10 Gbps.

The USB 3.0 Promoter Group has put the final draft of the specification for review.
