Abstract
In a differential signal test mode, the first control circuit causes, in response to the first control signal, the differential signal generating circuit to generate the differential signal depending upon the data signal and output the differential signal. The second control circuit stops the operation of the common mode signal generating circuit in response to the second control signal. In a common mode signal test mode, the first control circuit causes, in response to the first control signal, the differential signal generating circuit to generate a fixed differential signal and output the differential signal. The second control circuit causes, in response to the second control signal, the common mode signal generating circuit to generate the common mode signal depending upon the clock signal and output the common mode signal.
