ABSTRACT:
An output circuit includes a differential section configured to amplify an inputted differential signal; a current source section configured to supply a current to the differential section; a load resistance section connected with the differential section; and a control unit configured to set a value of the current from the current source section and a resistance value of the load resistance section based on a signal supplied to the control unit. The output circuit converts the differential signal into an output signal of a different interface level from that of the differential signal and balance-transmits the output signal.
