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.

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 Host to Device Platform-to-Platform with Ellisys Protocol Analyzer

We showed you our USB 3.1 Host and Device, Platform to Platform demonstration all the way back on November 8 (read the Nov 19 updated blog entry), so we thought we should prove we actually are running USB 3.1 transactions. We invited Chuck Trefts from Ellisys to bring in their USB 3.1 analyzer. It’s a small gold box, that looks more like a consumer device than an analyzer that belongs in a lab.
