A position-measuring device includes a position-sensing unit, a processing unit, an interface unit, a clock generator and a time measurement unit position-sensing unit configured to generate digital position values. The processing unit processes instructions from subsequent electronics. The interface unit communicates with the subsequent electronics, according to rules of an interface protocol, via at least one interface line that transmits interface signals having a temporal behavior that is determined by the interface protocol so as to transmit the instructions from the subsequent electronics to the processing unit. The clock generator generates a clock signal that serves as a time base for functions of the position-sensing unit and the processing unit. The time measurement unit uses the clock signal as a time base, receives at least one interface signal and measures a time interval between a start event and a stop event of the at least one interface signal.
