USB Type-C: One Plug to Rule Them All?
USB has become ubiquitous in consumer electronics, and USB Type-C provides a major upgrade. Starting with a small, reversible connector, it promises to provide all necessary external data and power connectivity for a range of devices from phones through servers. It also supports multiple, simultaneous, reversible data connections, and can sink or source up to 100W of power – thus enabling “one cable” docking solutions.
However, not all USB Type-C sockets are created equal. While they all have the same mechanical characteristics, they can provide different levels of functionality. To achieve maximum generality and to enable very low cost systems, a system need only implement a small fraction of the potential functions of the socket – and even within a system, an OEM may choose to provide asymmetric functionality on the multiple Type-C sockets on his system in the interest of saving cost. While engineers know that a 5W phone charger is not going to charge a laptop as quickly as a 60W power brick, this distinction may be lost on the general public when both chargers have the same mechanical connection to the system.
In this talk, Ken Shoemaker will elaborate about the various functions available over USB Type-C, and will give an overview of the mechanical, electrical and protocol specifications used to control these various functions.
