ABSTRACT:
In a data transfer device which cancells an offset of a differential amplifier for amplifying a received signal and an offset caused by characteristics of a differential transmission line and selects optimum conditions such as pre-emphasis amount of an output pre-emphasis circuit, a first chip (transmission side LSI=transfer engine210) and a second chip (reception side LSI=multiplexing engine330) are connected to each other through differential transmission line430and a SerDes (serializer)401and a SerDes (deserializer)402are used to make signal transmission, so that optimum setting conditions of an offset amount of an offset cancellation circuit included in an input buffer amplifier and a pre-emphasis amount of pre-emphasis circuit included in an output buffer are decided in training using a training PRBS generator560and a training PRBS comparator570.
