Abstract: A communication interface circuit includes a protocol layer circuit that generates packet data based on input data, and a physical layer circuit that encodes the packet data to output a transmission state, and drives a data lane including a plurality of three-phase wire links based on the transmission state, wherein the physical layer circuit may include an encoder that calculates the transmission state based on a preceding state output from the encoder in a previous unit interval, a symbol mapped to the packet data, and a control code, and wherein the control code instructs an encoding change based on a coupling relationship of the plurality of three-phase wire links. The communication interface circuit stably transmits data.
