Abstract
In versions 1.1a and 1.2 of the DISPLAYPORT™ standard, capacitors are used between a sourcing circuit and a switch for the auxiliary channel. As a result, these capacitors are generally uncharged when the switch activates the auxiliary channel, which can result in errors. Here, a switch is employed that uses precharge circuits to precharge these capacitors. Thus, errors due to charging of these capacitors can be reduced.
