1. A modular, numerical control unit having low-jitter synchronization, comprising:

  • a main computer; and

    at least one controller unit, the at least one controller unit, starting from the main computer, interconnected by serial data transmission channels in the form of a series circuit, the at least one controller unit including;

    a first receiver unit adapted to receive a serial data stream arriving from a direction of the main computer;

    a first transmitter unit adapted to output a serial data stream; and

    a clock recovery unit adapted to derive a synchronous clock signal from the serial data stream arriving at the first receiver unit and to supply the synchronous clock signal to the first transmitter unit, the synchronous clock signal used by the first transmitter unit as a transmission clock signal, the serial data stream arriving at the first receiver unit and the serial data stream output by the first transmitter unit coupled to each other in phase-locked manner.
