The present disclosure may provide an apparatus and a method for independent phase adjustment of a PAM receiver. The apparatus may comprise: a plurality of samplers configured to perform sampling for signal level determination of multilevel input data; a global clock source configured to provide a common sampling clock to the samplers; and a plurality of phase adjusters, each configured to adjust the phase of the common sampling clock so as to provide a sampling phase applied to a corresponding sampler. According to the present disclosure, even in a state where there are unsymmetric eye openings, reliable BER performance can be achieved by independently adjusting a sampling phase of a sampler corresponding to each eye opening.
