Receiving device, electronic device and system having the same

A system comprising:

• a transmitting device configured to output a data signal to a channel comprising a plurality of lanes;
• and
• a receiving device configured to receive the data signal from the channel,
• wherein the receiving device comprises:
• an equalizer configured to apply a gain value to a frequency range component of the data signal;
• and
• a control unit configured to determine the gain value based on temperature information, and generate a gain control signal for controlling the equalizer to apply the gain value.
