APPARATUS FOR RECEIVING DATA AND SYSTEM FOR TRANSMITTING DATA, CAPABLE OF PERFORMING ACCURATELY LEVEL DETERMINATION ON RECEIVING SIGNAL

摘要

PURPOSE: An apparatus for receiving data and a system for transmitting the data are provided to increase accuracy of multi-level data transmission by accurately performing a level determination on a receiving signal. CONSTITUTION: A data reception apparatus performs a data reception by a current signal. A receiving signal generator(22) includes a resistance circuit(222) and generates a receiving signal from a voltage generated by forcing the current signal to flow on the resistance circuit. A reference signal generator(23) includes a resistance circuit(232) and receives a reference current to be a generating source of the current signal to generate a reference signal from a voltage generated by forcing a current whose generating source is the reference current to flow on the resistance circuit. A logic determining unit(24) performs a multi-level determination on a receiving signal based on the receiving signal generated by the receiving signal generator and the reference signal generated by reference signal generator.
