Relationships Between USB Specs, Part Two & Where to Learn more about Type-C and DisplayPort alt mode

Recently I blogged on the relationships between USB Type-C, USB 3.1, Power Delivery and DisplayPort specifications. In my last blog I simplified the view focusing on the important and latest specifications. I think the simplified view answer most designer’s questions but there are still a few that like to see the full history and complex interactions. The below image, click to enlarge, provides a more detailed view of the different specifications, timeline representation and relationships.

What is USB Type-C anyway and what does it have to do with USB 3.1?

One of the challenges I had ramping back up on USB was understanding all of the advancements in the USB specifications since I last worked as part of the Synopsys DesignWare IP group. Of course along with the advancement of the USB specification also came a slew of new acronyms. Anything confusion I encountered was the connection between USB Type-C and USB 3.1. Apparently the confusion between USB Type-C and USB 3.1 is common as a simple search resulted in many technical article links, including the one below which I thought was a very good summary explanation.

Will USB Type-C burn my device?

I ran into this article online last week, http://www.laptopmag.com/articles/how-to-find-safe-usb-type-c-cables it discusses how a bad USB Type-C cable fried a Google engineers equipment, including a Chromebook Pixel. It also covers another issue when another bad Type-C cable drew too much power from a laptops port killing them. I highly suggest you read the article, but if you don’t have time then in summary; when a low quality, uncertified USB Type-C cable was used the incorrect resistance value for Type-C configuration causes the device to think it’s connected to a 3amp USB Type-C connection. Drawing 3A from a 500mA or 900mA port is not a good idea; the extra current draw damaged both devices. This issues reared its ugly head when using a USB Type-C to USB Type-A uncertified cable.
