Abstract: A device for monitoring operating parameters of integrated circuits. A signal is generated at least at one output of a comparison element by comparing switching states of input signals at the at least two inputs of the comparison element, which signal indicates that the at least one operating parameter has fallen below or has exceeded a predefined threshold. The two input signals are generated by at least two operating parameter-dependent devices, and the switching behavior thereof is subject to a time delay depending on the current value of the at least one operating parameter. A predefined time delay has a value such that when the predefined threshold of the operating parameter is exceeded, one of the input signals changes its switching state at the times predefined for the comparison element by the clock signal on the basis of the time delay.

Abstract: The invention relates to a bus coupler which converts a network-specific telegram arriving from an external network to an internal data telegram which transmits only the payload data from the network-specific telegram. The internal data telegram also contains at least one state information field for internal control information. The internal data telegram is transferred from the bus coupler to an internal bus system to which multiple bus users are connected in series. Each bus user connected to the internal bus system is able to monitor, in a decentralized and preferably autonomous manner, the communication quality of the lower-level bus system, and to initiate actions, depending on the implementation, on the basis of the internal control information received from the bus coupler, the internal control information generated by the particular bus user, and/or the internal control information received from the directly adjacent bus users.

Abstract: The invention describes a field bus system, in particular a field bus system (10), comprising at least one clocked transmitter (16) and one clocked receiver (17) for transmitting data signals to another field bus device (30) or for receiving data signals from the other field bus device (30). To allow interfering emissions to be reduced, a spread spectrum clock (40) is provided which supplies a local spread spectrum clock signal (SST1). The spread spectrum clock signal is sent to the transmitter (16) and the receiver (17) to allow data signals (DO1, DI1) to be transmitted and received synchronously with the local spread spectrum clock signal.
