Abstract
A clock and data recovery method comprising the following steps: an oversampling step wherein an oversampled stream of samples is generated from an input data stream at a data rate by using reference clock signal at a clock rate, the clock rate being higher than the data rate, and a tracking step of the input data stream realised by locating transitions between adjacent samples of the oversampled stream and by moving a no transition area within the oversampled stream wherein no transitions between adjacent samples are found a recovered data signal being obtained as a central portion of the no transition area and a recovered clock signal being obtained by dividing the reference clock signal. A clock and data recovery device is also described.
