Abstract

A device for synchronous serial data transmission over a differential data channel and a differential clock channel includes an interface controller having a clock generator, data controller, clock transmitter block and data receiver block. The clock generator generates a transmit clock signal which, during a data transmission cycle, includes a clock pulse train having a period. The clock generator is suitably configured such that, for data transmission cycles in a dynamic operating state in which a maximum occurring differential voltage of a differential clock signal is lower than a maximum differential voltage of the clock transmitter block, the clock generator sets a duration of a first clock phase of a first clock period of the clock pulse train to be longer than a first clock phase of following clock periods and shorter than a time duration required to reach the maximum differential voltage.
