Abstract
A device for extracting a clock frequency underlying a data stream includes means for controlling a controllable oscillator, coarse-tuning means and fine-tuning means, wherein coarse-tuning means responds to a second data pattern present in the data stream and sets the oscillator coarsely based on its length. Fine-tuning means responds to temporally consecutive first data patterns present in the data stream with a higher accuracy in order to perform a fine tuning of the oscillator on the basis of the temporal length between the two first data patterns and on the basis of the number of clock cycles of the controllable oscillator occurring in this temporal length.
