1. A method of link startup of a device comprising a plurality of lanes, the method comprising:
setting up data communication through a connected transmission lane and a connected reception lane from among the plurality of lanes;
setting a length of an activate period, in which a line of the connected transmission lane has a negative differential line voltage (DIF-N), to be less than a first time period;
transmitting, by the connected transmission lane, the activate period which is less than the first time period to the connected reception lane;
receiving, by the connected reception lane, the activate period being less than the first time period;
determining the activate period is less than the first time period; and
performing the link startup in a high-speed mode through the connected transmission lane and the connected reception lane, based on the activate period being less than the first time period.
