1. A method of generating a working clock in a module of a data transmission system, which comprises:

  • generating a synchronization clock signal in a control unit of the data transmission system in the form of voltage pulses;

    transmitting, with the control unit, the synchronization clock signal to the module of the data transmission system via a bidirectional interface;

    receiving the synchronization clock signal with a frequency-locked and/or phase-locked loop in the module;

    generating, with the frequency-locked and/or phase-locked loop a working clock on basis of the synchronization clock signal;

    controlling an operation of the module with the working clock; and

    transmitting data from the module to the control unit in the form of current pulses via the bidirectional interface.
