Abstract

See full text

In a circuit suppressing jitters without a synchronizing clock signal and an increase of a circuit scale, input data is regenerated by a data regeneration circuit in a broadband, a predetermined signal pattern which generates phase deviations exceeding a predetermined value is detected from the data regenerated by the data regeneration circuit by a pattern detection circuit, a reverse phase deviation signal having reverse phase deviations of phase deviations corresponding to the predetermined signal pattern is generated by a reverse phase deviation generating circuit, and an output signal of the data regeneration circuit is canceled by a phase deviation correcting circuit with the reverse phase deviation signal.
