Abstract
Four parallel lines are provided for the guided transmission of a data flow with a high rate (sub-GHz range). Two data bits per transmission clock are transmitted via these lines. The other two remaining lines are used for signaling certain changes in both data bits. Data transmission and signaling are accomplished on the basis of the Grey code. In other words, only one of the four lines changes state per clock. The interface according to the invention has reduced sensitivity to signal skew and permits simple clock recovery in terms of circuit engineering.
