The SuperSpeed lines on a USB-C port can be re-purposed to pass video data as well as USB data. Passing DisplayPort data over a USB-C connection is known as DP alt-mode. DP alt-mode can support two lanes of DP and two lanes of USB simultaneously, or four lanes of dedicated DP operation. DP alt mode requires a specialized MUX to handle the split between USB and DisplayPort data lanes. The TUSB564-Q1 is one such MUX that can be used on the DisplayPort sink side of the USB-C connection.
