TRANSMISSION MODULE FOR A TRANSMITTING/RECEIVING DEVICE OF A SUBSCRIBER STATION OF A SERIAL BUS SYSTEM, AND METHOD FOR TRANSMITTING A MESSAGE WITH DIFFERENTIAL SIGNALS IN A SERIAL BUS SYSTEM

A transmission module of a transmitting/receiving device for a subscriber station of a serial bus system and a method. The transmission module transmits a digital transmit signal as an analog differential signal on a bus of the bus system to transmit a message to another subscriber station. The transmission module generates the states, specified by the digital transmit signal over the time, on the bus by changing bus voltage and/or bus impedance. The transmission module changes the specified states on the bus via a predetermined sequence of intermediate states for the bus voltage and/or the bus impedance toward the desired state on the bus. The transmission module, when signaling changes during a transition between two specified states on the bus, changes the transition back again continuously with the opposite sequence of intermediate states from the intermediate state reached by then.
