Abstract
A data receiver and a method for adjusting the same are provided. The data receiver has an equalizer, a clock data recovery unit, an equalizer controller, and a decoder. The equalizer compensates incoming signal according to a configuration, and outputs corrected signal. The CDR unit uses a clock to sample the corrected signal from the equalizer and generates phase information of the clock. The decoder decodes the raw data. Each cycle of the clock is divided into a plurality of phases, and the phase information indicates the one of the phases that the corrected signal sampled therein. In a testing mode, the equalizer controller applies a plurality of setup values to the configuration individually and records the phase information for tuning the configuration. Therefore, the accuracy of the equalizer is improved and the good signal quality is obtained.
