Abstract:
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.

Claim (Index 1):
A receiver for multi-level pulse modulation comprising: a linear equalizer which amplifies a received signal; an analog-to-digital converter which converts an output from the linear equalizer into a digital value; a phase detector which detects advance and delay of a phase of a clock for a received signal on the basis of an output from the analog-to-digital converter; a decision feedback equalizer which filters the output from the analog-to-digital converter; a decision feedback equalizer with correction which filters and corrects the output from the analog-to-digital converter; and a data pattern filter which determines a phase and a data pattern on the basis of an output from the phase detector and an output from the decision feedback equalizer, and gives a correction amount to the decision feedback equalizer with correction, wherein the decision feedback equalizer with correction corrects received data to reduce errors.
