Abstract
A bit synchronization device which extracts an output data signal and an output clock signal from an input data signal on the basis of a multi-phase clock signal. The bit synchronization device is provided with a processing circuit which holds a phase corresponding to a change point of an input data signal with a multi-phase clock signal, and while the input data has a phase without change point, carrying out a data identification free from an error by selecting a clock signal corresponds to the phase without change point.
