A data transmission device is applied to a network apparatus having an automatic crossover function, and is connected to a transmission control unit, such that the transmission control unit detects an operating status of the network apparatus and accordingly generates a control command. Thereby, a current source generating unit provides current sources to a first-mode converting unit and a second-mode converting unit according to the control command. This allows a suitable data transmission processing mode to be selected automatically and instantaneously for the operating status of the network apparatus by the current sources from the current source generating unit and the control command generated from the transmission control unit, so as to achieve power saving, low distortion and/or anti-interference.
