A look-ahead decision feedback equalizing receiver includes an equalizing block for amplifying a high-frequency component of an external data signal fed thereto in response to a predetermined first input signal and a predetermined second input signal, to provide a first equalized external data signal and a second equalized external data signal, respectively; a clock synthesizer for outputting a plurality of sampling clocks, a timing thereof being adjusted by receiving an external clock synchronized with the external data signal; an over-sampler for over-sampling the first equalized external data signal and the second equalized external data signal in synchronization with the sampling clocks; a MUX block for multiplexing the outputs of the over-sampler in response to preceding outputs of the MUX block, which are fed back thereto, to thereby attain MUX decision results; and a phase detector for deciding the timing of the sampling clock by analyzing the MUX decision results.
