Patent ID: 8030984

Claim:
An electronic circuit for extracting clock signal from an incident sequence of binary data, comprising: an input terminal configured to receive the incident sequence; an oscillator configured to provide a sinusoidal signal having a frequency controlled by a control voltage; a circuit connected to the input terminal and configured to extract transition edges of the incident sequence and configured to provide successive brief pulses at the transition edges; a sampler configured to receive the brief pulses and the sinusoidal signal for tapping off level of the sinusoidal signal at instants of the brief pulses; and an integrator connected to an output of the sampler for integrating the level in tandem with the successive brief pulses, the integrator having an output of the control signal connected to an input of the oscillator, wherein the oscillator is configured to provide the sinusoidal signal as the clock signal extracted from the incident sequence of the binary data with a slaved phase relative to the transition edges of the binary data.
