Provided is an electric signal transmission device which corrects a data error caused by data transition in a pulse amplitude modulation signal to increase an EYE width. The electric signal transmission device can operate as follows: A data pattern determined by an equalizer and a phase relationship between data and a clock detected by a phase detector are used to calculate a correction amount according to the data pattern and the phase relationship, and the received data is corrected to a correct value by adding a correction amount in a data transition direction.
