Abstract
To compensate for intersymbol interference, a serial data receiver circuit included in a computer system may include an equalizer circuit that includes a digital-to-analog converter circuit. Based on previously received symbols, the equalizer circuit modifies a signal received via a communication channel or link prior to clock and data recovery. In cases when the digital-to-analog converter circuit becomes saturated, the equalizer circuit additionally uses a dither signal to modify the received signal.
