Clock regeneration apparatus and electric equipment

Abstract

Disclosed herein is a clock regeneration apparatus, including: an oscillator including n (an integer of two or more) gating groups connected in cascade connection to each other forming an oscillation loop, the gating groups being controlled to gate an internal clock signal with first to nth gating signals different from one another, respectively, the oscillator outputting a clock signal at least from the nth one of the gating groups; an edge detection section adapted to detect an edge of a reception data signal; a phase decision section adapted to decide a phase of the clock signal for each edge of the reception data signal and output a result of the decision as a phase decision signal; and a gating signal generation section adapted to generate the first to nth gating signals and output the gating signals to first to nth ones of the gating groups, respectively.
