Abstract
A receiver circuit includes an equalizer configured to generate an equalization signal by equalizing an input data signal transferred through a communication channel based on an equalization coefficient; a clock data recovery circuit configured to generate a data clock signal and an edge clock signal based on the equalization signal, generate a data sample signal including a plurality of data bits by sampling the equalization signal in synchronization with the data clock signal, and generate an edge sample signal including a plurality of edge bits by sampling the equalization signal in synchronization with the edge clock signal; and an equalization control circuit configured to control the equalization coefficient by comparing the plurality of data bits and the plurality of edge bits.
