PROBLEM TO BE SOLVED: To provide a data transmission system that can be miniaturized and can transmit data at a relatively high frequency and feed power with a pair of transmission lines. SOLUTION: A data transmitter comprises: a parallel/serial converter for converting a parallel data signal of a plurality of bits to a serial data signal from which a DC current component is removed; a differential current mode logic converter for converting the serial data signal to a differential current mode logic; a capacitor that passes a differential serial data current to a data receiver from the differential current mode logic converter, and breaks a DC current to a differential current mode logic conversion means from the data receiver; a constant voltage generator for feeding power to each section with a preset voltage level; and a filter that passes the DC current to a constant voltage generation means from the data receiver, and breaks a differential serial data current to the constant voltage generation means from the differential current mode logic conversion means.
