Phase error detection device, phase error detecting method, integrated circuit and optical disc device

A phase error detecting method for detecting 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 detecting method comprising:
• a phase error generating step of generating the phase error from the output from the A/D conversion section;
• and
• a phase error correcting step of correcting the phase error, wherein:
• in said phase error correcting step a phase error detection range is determined from past phase errors and the phase error is corrected when the phase error generated in the phase error generating step is out of the phase error detection range.

An integrated circuit comprising:
