摘要:
An electronic device includes an integrated circuit, a connector, and a circuit board. The integrated circuit includes a first signal processing circuit, a second signal processing circuit, and an interface multiplexer having a first input port electrically connected to the first signal processing circuit, a second input port electrically connected to the second signal processing circuit, and an output port arranged to be electrically connected to the first input port or the second input port. The circuit board carries the integrated circuit and has a plurality of connector placement sites, including at least a first connector placement site each dedicated to the first signal processing circuit and at least a second connector placement site each dedicated to the second signal processing circuit. The connector placement sites and the output port of the interface multiplexer are electrically connected in series. The connector is installed on one of the connector placement sites.

摘要:
A control chip includes a configurable pin and a control logic. The configurable pin is arranged for coupling a first pin and a second pin of a high-definition multimedia interface (HDMI) connector. The control logic is arranged for controlling the configurable pin to switch between a first operation mode and a second operation mode. The configurable pin serves as an input pin when operating in the first operation mode, and the configurable pin serves as an output pin when operating in the second operation mode. For example, the input pin is arranged for receiving a power supply signal derived from a +5V power signal received by the first pin, and the output pin is arranged for outputting a control signal for controlling hot plug detection (HPD).
