摘要： A receiver configuration for a control unit in a vehicle having a voltage generator for generating a synchronization pulse, which includes a first voltage source, a current source and a current sink, the voltage generator generating the synchronization pulse within predefined specification limits having a predefined shape and a predefined time behavior, and the receiver configuration outputting the synchronization pulse for synchronizing a signal transmission via a databus to at least one sensor. A method is also provided for generating a synchronization pulse. The voltage generator generates the synchronization pulse via the current source and the current sink by charging and/or discharging a bus load essentially as a sinusoidal oscillation.

摘要： A method for ascertaining a load capacitance of a data bus includes reading in and a determining task. In the reading in, a scaling factor of a synchronization pulse of the data bus is read in. In the determining, the load capacitance is determined using the scaling factor and a processing rule.

摘要： A digital communication system user, via which a first logic signal and a second logic signal are transmitted, includes an activation circuit that includes encompassing a supply unit, a switching unit, a transmission unit, and a communication interface. The supply unit provides an internal supply voltage, the switching unit couples the supply unit to the transmission unit to supply the transmission unit with the internal supply voltage, and the transmission unit outputs a wake-up signal, which includes the first logic signal, to the communication interface in response to being supplied with the internal supply voltage by the supply unit, and subsequently continuously outputs the second logic signal to the communication interface until the switching unit separates the transmission unit from the supply unit by.
