Differential signaling serial interface circuit

PURPOSE: A differential signaling serial interface circuit is provided to prevent the attenuation of an output voltage by embedding a termination resistance into a receiver. CONSTITUTION: A receiver includes a voltage comparator. A termination resistance is formed in the input terminal of the voltage comparator. A panel is formed on the end of the receiver in order to have a constant load. A transmitter supplies a differential input current to the load of the panel. A differential signaling serial interface circuit is a push-pull type circuit.
