ABSTRACT:
An electronic control module reduces ringing in the digital signals on a transmission line which has multiple transmitters, receivers, and parasitic inductors and capacitors coupled to the line. Preferably, a copy of this control module is provided at each node on the line which has a transmitter and/or receiver. Each copy of the control module has three main parts--a sensing circuit, a pulse generating circuit, and a switching circuit. The sensing circuit is coupled to the transmission line, and it generates a control signal when the digital signal on the transmission line changes from a low voltage to a high voltage. The pulse generating circuit receives the control signal and responds by generating a single pulse. The switching circuit receives the pulse and, in response, couples a high supply voltage to the transmission line while the pulse occurs.
