Abstract:
1. A receiver circuit for receiving a received signal that propagates through a transmission medium, comprising: an equalizer that equalizes the received signal; a data detection circuit that detects an analog output signal of the equalizer at a data sample timing and outputs a digital signal; an intersymbol interference detection circuit that detects an intersymbol interference level from the analog output signal of the equalizer at the data sample timing and from the digital signal; an equalizer characteristic control unit that controls the characteristic of the equalizer to minimize the intersymbol interference level detected by the intersymbol interference detection circuit; and a data sample timing control unit in which the data sample timing is controlled to a first data sample timing at which the difference between the amplitude of the analog output waveform of the equalizer with respect to an impulse and an amplitude of an ideal impulse response waveform is minimal.
