More Information
Summary:A HDMI (High-Definition Multimedia Interface) transmitter component may be operated solely on power that is scavenged and converted from termination tail current received while the HDMI transmitter component is coupled to an HDMI compliant sink connector on a HDMI receiver component. The termination tail current is received at the transmitter component from a plurality of differential HDMI signals from terminators on a receiver component. A portion of the received tail current is converted to form a supply voltage Vdd source. Function logic on the transmitter component is operated using the Vdd voltage, and the function logic is configured to control the plurality of differential signals.
