8. A method of independent phase adjustment of a pulse amplitude modulation (PAM) receiver including a plurality of samplers and a plurality of phase adjusters, the method comprising:
determining a maximum height of each eye opening of a plurality of eye openings of multi-level input data;
determining respectively a phase corresponding to the maximum height of each eye opening;
adjusting respectively a phase of a common sampling clock provided from a global clock source to a determined phase in a phase adjuster corresponding to each eye opening; and
sampling the multi-level input data by a sampler corresponding to each phase adjuster using the adjusted phase as a sampling phase.
