Transmitting / receiving device for a bus system and method for reducing a tendency to oscillate when passing between different bit states

摘要

There is provided a transmission / reception means (12; 120; 1200) for a bus system (1) and a method of reducing a tendency to oscillate in the transition between different bit states. The transmitting / receiving device (12; 120) has a receiving comparator (1221) for receiving a signal which is transmitted from a bus (40) of the bus system (1), at which bus system (1) at least temporarily an exclusive, collision-free access Subscriber station (10, 20, 30) on the bus (40) of the bus system (1) is ensured, and a vibration reduction unit (15; 150) whose input is connected in parallel to the input of the receiving comparator (1221), wherein the vibration reduction unit (15 150) is configured to connect at least one bus wire (41; 42) of the bus (40) to a bus bias potential upon detecting a state transition of the received signal from a dominant bus state (402) to a recessive bus state (401).
