Abstract
An signal communication device having an auto-configured equalizer. The signal communication device includes a scoping circuit, buffer circuit, select circuit and equalizing circuit. A test signal is transmitted to the signal communication device via a signal path. The scoping circuit generates a waveform trace of the test signal, the waveform trace indicating time interval between receipt of a transition in the test signal and receipt of a reflection of the transition. The buffer circuit stores a plurality of data values that correspond to data signals received via the signal path. The select circuit selects one of the plurality of data values from the buffer circuit based on the time interval indicated by the waveform trace. The equalizing circuit generates an equalizing signal based on the selected data value.
