USB – Greening the Earth with USB Type-C (and actual plants) USB Type-C standardizes power across devices, across continents, across oceans.
Thanks to the huge consumer demand for increased safety, autonomous driving and improved luxury in vehicles the automotive SoC market is expected to grow at 6.7% CAGR between 2014 to 2019 (source IC Market Drivers, IC Insights Jan 2016).
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.

State of USB Spring 2016 – Part 3 (and Snail Jokes)
I’m super excited to announce we certified our 10 Gigabit per second USB 3.1 Gen 2 controller and PHY IP. (One month ago.) (When Mick blogged about it right here)
The big question on people’s minds is if wireless, data transfer and charging, will replace USB in the future. The simple answer is NO, USB is here to stay. For the longer answer read on.
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.
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.
USB 3.1 Chips in Laptops I’m super excited to report that USB 3.1 Gen 2 is now shipping (will be shipping soon) in laptops. Yes Laptops! This is about 6 months before I expected it to happen.
