Abstract:
1. A transmission circuit adapted for an input and output (I/O) interface, the transmission circuit comprising: an equalizer circuit receiving an input signal and performing an equalizing operation on the input signal according to a plurality of preset state values to output an equalizing signal corresponding to each preset state value; a slicer circuit coupled to the equalizer circuit, receiving the equalizing signal, and performing a slicing operation on the equalizing signal to output a slicing signal; a signal detection circuit coupled to the slicer circuit, and detecting and comparing the equalizing signal and the slicing signal to adjust the equalizer circuit to one of the preset state values; and a control circuit coupled to the slicer circuit for receiving the slicing signal corresponding to each preset state value, comparing the slicing signal corresponding to each preset state value with a plurality of signal patterns to generate a comparison result, and selecting one of the preset state values according to the comparison result to let the equalizer circuit perform the equalizing operation according to the selected preset state value.
