Abstract

A receiver includes a receiver clock oscillator controllable with regard to its receiver oscillator frequency, means for detecting a number of clock periods that the receiver clock oscillator performs in a specifiable period of time, means for extracting a first and a temporally following second reference entry in a received data stream, wherein means for extracting is implemented in order to control means for detecting on the basis of the extracted first and second reference entry with regard to the specifiable period of time, and means for comparing the number of clock periods of the receiver clock oscillator with the information in the second reference entry in order to control the controllable oscillator depending on a comparison result so that the oscillator frequency is increased or decreased so that the oscillator frequency is in a predetermined ratio to a frequency of the clock oscillator in the transmitter or is equal to the frequency of the clock oscillator in the transmitter. This way, in a simple and secure way, without slow phase-locked loops for a jitter suppression, it is guaranteed that the receiver is fixedly synchronized with the transmitter and that simultaneousl…
