Transmission/reception device and information processing device

An information processing device comprising:

• a first delay application unit configured to apply a delay to at least one of a positive signal and a negative signal of differential signals to be sent;
• a first skew detection unit configured to detect a differential signal skew between the positive signal and the negative signal;
• a first semiconductor integrated circuit including a transmission circuit including a first control unit configured to control the first delay application unit in a manner as to reduce the differential signal skew detected by the first skew detection unit, the first semiconductor integrated circuit being configured to send the differential signals from the transmission circuit to outside;
• a second delay application unit configured to apply a delay to at least one of a positive signal and a negative signal of differential signals sent from the first semiconductor integrated circuit;
• a second skew detection unit configured to detect a differential signal skew between the positive signal and the negative signal received from the first semiconductor integrated circuit, or between the positive signal and the negative signal to at least one of which the delay is applied by the second delay application unit;
• and
• a second semiconductor integrated circuit including a reception circuit including a second control unit configured to control the second delay application unit in a manner as to reduce the differential signal skew detected by the second skew detection unit, the second semiconductor integrated circuit being configured to receive, by the reception circuit, the differential signals sent from the first semiconductor integrated circuit.
