Abstract: A data clock signal for data in an incoming signal is generated by means of a clock recovery module. The incoming signal consists of a data burst having a periodic preamble followed by a data sequence. The clock recovery module comprises a first clock generator, a sampling device, a correlator, a control unit and a time registration device. The clock generator generates a clock signal having a first clock frequency which is a factor N higher than the frequency of the preamble. The sampling device samples the incoming signal at the first clock frequency. The correlator correlates the sampled signal with a predefined correlation word, the correlation between the incoming signal and the correlation word being represented as a correlation signal in the form of a series of discrete correlation signal values. The control unit detects local extreme values for the correlation signal.
