Type-C USB cable adapter design consideration app note from Fairchild Semiconductors. Link here (PDF)

USB is a ubiquitous connector that is used by many customers and in many different applications. With the official release of the USB Type-C connector, many companies are racing to implement this new connector and the supporting infrastructure. The early adopters of this connector will be faced with many challenges as different vendor’s release products that are either non-compliant or designed to earlier versions of the specification.

One specific challenge is with USB Type-C adapter cables and how they are implemented. The adapter cables are critical for new designs because they allow backward compatibility to the existing USB infrastructure. Vendors are making a wide range of adapter cables which can cause detection issues which need to be considered. This application note describes these considerations and possible solutions to the problems faced.
