Abstract:
1. A device capable of selecting one equalizing mode from a plurality of equalizing modes, comprising: a programmable equalizer, having said equalizing modes, for receiving an original signal to output an equalized signal; a phase-locked loop, receiving a reference clock signal and a first control signal so as to output first sampling pulses and second sampling pulses; a data slicing device, coupled to said phase-locked loop and said programmable equalizer, for receiving said first sampling pulses, said second sampling pulses and said equalized signal to output a first slicing signal and a second slicing signal; and a signal processing device, coupled to said data slicing device, for receiving said first slicing signal and said second slicing signal to output said first control signal and a second control signal; wherein said signal processing device programs said programmable equalizer according to said second control signal so as to select said equalizing mode from said plurality of equalizing modes for said programmable equalizer.
