Abstract
In some embodiments, the present disclosure provides techniques for concurrently exchanging USB 2.0 information, SuperSpeed information, and four lanes of DisplayPort information via a single USB Type-C connection. In some embodiments, this may be accomplished in part by multiplexing signals such as the USB 2.0 signals and the DisplayPort AUX signal to fewer than a standard number of conductors in order to free up other conductors for the third and fourth lanes of DisplayPort information. In some embodiments, a standard USB Type-C receptacle, plug, and cable are used. In some embodiments, a modified receptacle, plug, and/or cable are provided.
Claims24
A system for communicating USB and DisplayPort information via a USB Type-C receptacle, the system comprising:
- a computing device comprising:
- a USB host controller that includes a USB 2.0 differential pair;
- a DisplayPort source graphical processing unit (GPU) that includes an AUX differential pair;
- a USB Type-C receptacle;
- and
- a switching device that includes a multiplexer (MUX) device;
- wherein the USB 2.0 differential pair and the AUX differential pair are selectively coupled to the MUX device by the switching device;
- and
- wherein the MUX device is configured to enable communication via both the USB 2.0 differential pair and the AUX differential pair via a configuration channel (CC) pin of the USB Type-C receptacle.

A switching device for coupling a USB host and a DisplayPort source to a USB Type-C receptacle, the switching device comprising:
- a set of conductors configured to be coupled to pins of the USB Type-C receptacle;
- a set of conductors configured to be coupled to SuperSpeed conductors of the USB host;
- a set of conductors configured to be coupled to DisplayPort lane conductors of the DisplayPort source;
- and
- a multiplexer (MUX) device;
- wherein the switching device is configured to selectively couple the MUX device to USB 2.0 conductors of the USB host and to AUX conductors of the DisplayPort source;
- and
- wherein the MUX device is configured to combine signals from the USB 2.0 conductors and the AUX conductors for communication via at least one pin of the USB Type-C receptacle.
16-25. (canceled)
A system for communicating USB and DisplayPort information via a USB Type-C receptacle, the system comprising:

- a USB Type-C receptacle that includes a first side band use (SBU) pin and a second SBU pin;
- and
- a switching device that includes a multiplexer (MUX) device;
- wherein the USB 2.0 differential pair and the AUX differential pair are coupled to the switching device;
- wherein the switching device is configured to selectively couple the USB 2.0 differential pair and the AUX differential pair to the MUX device;
- and
- wherein the MUX device is configured to enable communication via both the USB 2.0 differential pair and the AUX differential pair via the first SBU pin and the second SBU pin.
