Abstract
Disclosed are an image generating device and a communication circuit thereof. The communication circuit includes a first pull-up resistor, an unidirectional current component, a signal isolation component and a signal switch. The first pull-up resistor receives a standby voltage. The unidirectional current component is coupled between the first pull-up resistor and a (CEC) pin. The signal isolation component is coupled to a path between the pin CEC and the signal switch, where a first end of the signal isolation component is controlled by the standby voltage. The signal switch is coupled to a second end of the signal isolation component, and the signal switch couples the second end of the signal isolation component to a second pull-up resistor of a processor or the signal switch couples the second end of the signal isolation component to a third pull-up resistor of a port according to a system voltage.
