Patent ID: 7999802

Claim:
An interface system, comprising: a serializer for receiving a first data and second data having a plurality of bits from an external device, and sequentially outputting of the received first data and second data in two bits; a transmission circuit coupled to the serializer, comprising: a decoder for converting the two bits supplied from the serializer into three bits; a driver for controlling a flow of electric current to correspond to the three bits; and a transmission resistor to which a voltage is applied to correspond to the flow of the electric current; a reception circuit coupled to the transmission circuit, comprising: a reception resistor for receiving a voltage supplied the transmission resistor; amplifiers for amplifying a voltage applied to both ends of the reception resistor; comparators for recovering the three bits by comparing the voltage supplied to the amplifiers; and an encoder for recovering the two bits using the three bits; a deserializer for recovering the first data and the second data while sequentially storing the two bits supplied from the reception circuit; and stabilization circuits for controlling the transmission circuit.
