Abstract: A data communication device comprises an input circuit (DRTC) that converts external data (XDT) into internal data (IDT) on the basis of a sampling signal (SP). A synchronization circuit (SYNC) provides the sampling signal (SP) on the basis of an oscillator signal (OS) and a synchronization value (SV). The synchronization value (SV) is representative of a number of cycles of the oscillator signal (OS) contained within a time interval for a unit of external data. The synchronization value (SV) is an initial value (IV) during an initial synchronization phase and a measured value (MV) during a measurement-based synchronization phase. A control circuit (IFC) carries out a calibration step in which the initial value (IV) is a preprogrammed reset value (RV) and in which the measured value (MV) is stored as a calibration value (CV). The control circuit (IFC) applies the calibration value (CV) as the initial value (IV) in subsequent initial synchronization phases.
