APPARATUS AND METHOD FOR PHASE ADJUSTMENT OF RECEIVER FOR PAM SIGNALING

The present disclosure may provide a device and method for independent phase adjustment of a PAM receiver. The device includes: a plurality of samplers configured to perform sampling for signal level decision of multi-level input data; a global clock source configured to provide a common sampling clock to the samplers; and a plurality of phase adjusters configured to respectively adjust a phase of the common sampling clock to provide a sampling phase applied to a corresponding sampler. According to the present disclosure, it is possible to achieve reliable BER performance by independently adjusting a sampling phase of a sampler corresponding to each eye opening even in the presence of unsymmetric eye openings.
