DEVICES AND METHODS FOR PROVIDING CONCURRENT SUPERSPEED COMMUNICATION AND FOUR-LANE DISPLAYPORT COMMUNICATION VIA A USB TYPE-C RECEPTACLE

摘要

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.

主权项

1. 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; anda 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.
