Abstract

A data transfer device for unidirectional serial data transfer from a transmitting device to a receiving device, in particular from a microcontroller to an output stage IC of a motor vehicle control unit. The data transfer device includes a P/S converter provided in the transmitting device for converting a parallel data stream made available in the transmitting device into a serial data stream with transfer frames of a predefined format and for transmitting the serial data stream to the receiving device over a data transfer channel. The data transfer device also includes an S/P converter provided in the receiving device for converting the transmitted serial data stream back into a parallel data stream, and a clock signal generating device for generating a clock signal and for sending the clock signal to the P/S converter and the S/P converter to perform the conversion operations continuously and in-phase. In addition, the data transfer device includes a synchronizing device for generating a synchronizing signal according to the conversion operation of the P/S converter and for supplying the same to the S/P converter for synchronizing the conversion operations.
