Abstract
A signal receiving device and an equalizer tuning method thereof are provided. A first equalizer receives an input signal and generates a first equalized signal by compensating the input signal according to a first equalization parameter. A second equalizer generates a second equalized signal by compensating the first equalized signal according to a second equalization parameter. A clock and data recovery circuit recovers the second equalized signal to generate an output signal. An equalizing controller receives the input signal and outputs a first control signal and a second control signal, to adjust the first equalization parameter according to the first control signal and adjust the second equalization parameter according to the second control signal. The equalizing controller detects a first pattern symbol and a second pattern symbol from the output signal and tunes the second equalization parameter according to the number of the first pattern symbol and the second pattern symbol.
