ABSTRACT:
A clock generating apparatus and clock generating method of an optical disc drive for calibrating a clock signal according to an input signal. The clock generating apparatus includes a frequency detector for detecting sampling times in a duration when the clock signal samples an interval between two synchronization patterns of the input signal, and for generating a first adjusting signal according to the sampling times, and a signal generator electrically coupled to the frequency detector for calibrating the clock signal according to the first adjusting signal.
