Abstract
A bus line is provided with broadly distributed signal termination by using switched termination logic where the pull up resistance of a driver corresponds to the characteristic impedance of the line and the pull down resistance of the driver corresponds to the number of drivers coupled to the line. Accordingly, signals being transmitted over the bus suffer relatively few reflections thus advantageously producing a shortened signal settling time, thereby increasing the attainable signaling frequency.
