Abstract
A phase error detection device detects a phase error, based on an output from an A/D conversion section that performs A/D conversion on an analog input signal in accordance with a sampling clock to generate a digital reproduction signal. The phase error detection device includes a phase error generation section that generates the phase error from the output from the A/D conversion section, and a phase error correction section that corrects the phase error. Herein, the phase error correction section determines a phase error detection range from past phase errors and, when the phase error generated by the phase error generation section is out of the phase error detection range, corrects the phase error.
