Abstract
A data discriminating circuit is provided on the receiver side of a digital signal transmission system, and performs data discrimination with a proper phase relation settled between data and a clock signal. In the discrimination circuit, a data discriminating section discriminates input data in synchronism with a clock signal and outputs resultant data as discriminated data, a phase-relation judging section judges a phase relation between the input data and the discriminated data, a clock phase controller produces a phase control signal to control and initially-determined phase of the clock signal, based on an output of the phase-relation judging section, and a clock phase judging section determines a phase of the clock signal and alters the initially-determined phase of the clock signal in accordance with the phase control signal from the clock phase controller.
