Abstract
A device for a serial bus system. The device includes a receiver for receiving a signal from a bus of the bus system, in which bus system at least one first communication phase and one second communication phase are used for exchanging messages between user stations of the bus system. For a message, the bus states of the signal received from the bus in the first communication phase are different from bus states of the signal received in the second communication phase. The receiver is designed to generate a digital signal from the signal received from the bus and to output the signal to a communication control device which evaluates data contained in the digital signal. The receiver uses a first reception threshold and a second reception threshold in each of the communication phases for generating the digital signal, and the second reception threshold has a negative voltage value.
