  • Publication number: 20130187699
    Abstract: A circuit for switching between an AC-coupled connectivity and DC-coupled connectivity of a multimedia interface. The circuit comprises a current source connected in series to a wire of the multimedia interface and a coupling capacitor; and a termination resistor connected to the current source and to the coupling capacitor, wherein the circuit is connected in series between a source line driver and a sink line receiver of the multimedia interface, wherein the source line driver supports both the AC-coupled connectivity and the DC-coupled connectivity and the sink line receiver supports any one of the AC-coupled connectivity and the DC-coupled connectivity, wherein the current source and the termination resistor allows the setting of voltage levels of signals received at the sink line receiver to voltage levels defined by the multimedia interface thereby to switch to the coupling connectivity type required by the multimedia interface at which the sink line receiver operates.
