Abstract:
1. In a circuit configuration for processing data, having a control circuit configured to set a phase or a frequency of a second signal with a prescribed phase or frequency relationship with respect to a first signal, said control circuit having a digital counter for detecting a phase or frequency difference between the first signal and the second signal, and said counter outputting a counter signal acting as a control signal of said control circuit for setting the phase or frequency of the second signal, the improvement which comprises: an evaluation circuit connected to receive the counter signal and configured to assess an operating state of the circuit configuration on a basis of a counter reading, said circuit configuration having parts, and said evaluation circuit switching at least said parts to a changed operating mode on the basis of the counter signal; and said parts affecting a clock frequency of the circuit configuration, and said evaluation circuit switching at least said parts affecting the clock frequency to a faster operating mode upon identification of a slow operating state in the circuit configuration.
