Abstract
A method for providing power to a boost device in a high-speed cable connected between a transmitting data source device and a receiving data sink device is described. The method comprises receiving differential data signals from the data source device in a differential input circuit of the boost device; boosting at least one of the received differential data signals into a boosted differential data signal; transmitting the boosted differential data signal from a differential output circuit of the boost device to the receiving data sink device; and obtaining power to operate at least some of the circuitry of the boost device from the data sink device through its connection with the differential output circuit, for example, providing at least some of the power to operate the processing block. A corresponding high-speed cable is also described.
