ABSTRACT:
An integrated circuit has connecting pads for outputting digital signals, a connection for a time reference signal, and an assessment circuit to measure and assess a phase shift between one of the digital signals and the time reference signal. A receiver circuit is connected to a respective junction between one of the connecting pads and an associated output driver. A device for matching propagation times of signals applied to the receiver circuit is provided. The assessment circuit is connected to the receiver circuit and has an output to output a measured result. In each case, the phase shift of the signals to be output in relation to the time reference signal is measured and assessed separately. An offset of the switching edges of the signals to be output can be determined relatively accurately and corrected.
