Abstract
A data discriminating circuit which discriminates a signal, particularly, a data discriminating circuit which can perform data discrimination with the proper phase relation settled between data and a clock with a simple circuit structure. The data discriminating circuit comprises a clock distributor for generating first and second clock signals having different phases, first and second data discriminating/judging sections for respectively receiving the first and second clock signals and commonly receiving data, and a discriminated-data selecting section, which receives first discriminated data discriminated with the first clock signal, a discrimination/judgment result based on the phase relation between the first discriminated data and the first clock signal, second discriminated data discriminated with the second clock signal, and a discrimination/judgment result based on the phase relation between the second discriminated data and the second clock signal, and selectively outputs the first or second discriminated data based on both discrimination/judgment results.
