Abstract
A receiver circuit includes a data interpolator to interpolate an input data signal and generate an interpolation data signal, a data determination unit to determine a data determination result of the interpolation data signal, a clock recovery unit to detect phase information based on a data determination result and output an interpolation code determining an interpolation rate to the data interpolator based on the detected phase information, a first interpolator to interpolate the input data signal and generate an interpolation data signal for an eye pattern monitor, a first determination unit for the eye pattern monitor to compare the interpolation data signal with a reference voltage, a match determination unit to determine whether the data determination result of the data determination unit matches a comparison result of the first determination unit, and an eye pattern regenerator to generate an eye pattern based on the phase information and a determination result.
