ABSTRACT:
A cascading differential signal circuit. The processor outputs a differential signal. The data-bus transmits the differential signal. Each driving IC comprises a data receiving circuit, a terminal resistor, an output terminal and an analog-digital converter. The data receiving circuit is coupled to the data-bus for receiving the differential signals and encoding a digital signal. The terminal resistor is coupled to the data receiving circuit for acquiring an impedance match with the data-bus to transmit the differential signals. The output terminal is coupled to the terminal resistor for outputting the differential signals. The analog-digital converter is coupled to the data receiving circuit for converting the digital signal to an analog signal.
