Abstract
A method of recovering a clock signal from a digital signal in a receiver includes generating a representation of an eye diagram from symbols of the digital signal, in which the symbols are sampled at a sample rate such that the representation of the eye diagram is generated by a plurality of samples. The generated representation is converted into an array of data elements having a first set of data corresponding to the plurality of samples, and a second set of data representing a plurality of data bins. A plurality of measurements are performed on the array of data elements and/or the eye diagram to obtain a plurality of measurement outputs corresponding to the plurality of samples, which are combined at each sample. A sample is selected as a clock sample based on results of the combination.
