ABSTRACT:
A clock phase acquisition/tracking device comprises a phase error operation section for operating a phase error of a quantized signal to a given quantization timing and a clock generation section for generating a clock at a given phase based on a phase error information operated in the phase error operation section. For the resulting quantized signal, a determination is made using a threshold set based on a previously quantized signal when the phase error is operated in the phase error operation section upon the beginning of the clock phase acquisition. Thus, the time necessary for the phase aquisition can be shortened.
