Abstract

A device for a serial bus system. The device has a receiver receiving a signal from a bus of the bus system. For a message exchanged between user stations of the bus system, a recessive bus state is overwritable by a dominant bus state and the recessive bus state is generated differently in the first communication phase than in the second communication phase. The receiver generates a digital signal based on the received signal, and the signal being output to a communication control unit for evaluating the data contained in the digital signal. The receiver uses a first and second reception threshold for generating the digital signal in the second communication phase, the second reception threshold having a voltage value lower than that of the first reception threshold or higher than the highest voltage value which, during normal operation, is established on the bus for a dominant bus.
