    摘要： Aspects of the present disclosure involve a circuit for delivering electrical power from a direct current voltage source to an electronic system. The circuit may include a power injection circuit that injects a first portion of the power from a supply voltage of the source to a first data line and a second portion of the power from the supply voltage to a second data line. The power injection circuit may include first and second conductive paths from the supply voltage to the first and second data lines having first and second inductances, respectively, as well as a third conductive path between the first and second data lines having a third inductance greater than the first and second inductances. A conductive support structure may carry return current from the electronic system to the source.

    摘要： Circuits, methods, and apparatus that provide for the powering of active components in connector inserts at each end of a cable may in various ways. For example, where a host is coupled to a device that is not self-powered, the host may provide power for circuitry at each end of the cable. In various embodiments of the present invention, the device may request higher voltage from the host, such that more power can be delivered. In these cases, the device may regulate the voltage received from the host to a lower voltage, and then provide the lower voltage to circuitry at one or both ends of the cable. Where the host is connected to a device that is self-powered, the host and the self-powered device may power their respective connector insert circuits.
