Abstract
A calibration device is coupled to a communication line shared by plural devices. The calibration device is configured to perform an iterative eye width scanning by adjusting a set voltage level by a preset level from a first voltage level to a reference center voltage level, wherein the first voltage level corresponds to a cross point where values of signals or data, which are transmitted via the communication lines, are changed in different directions; and determine, as a zero crossing for the signals or the data, a voltage level corresponding to a largest value among a plurality of eye widths obtained through the iterative eye width scanning.
