ABSTRACT:
Embodiments include systems and methods of powering data communications transmitter circuitry using current sinked from biasing circuitry used to bias a transmission line between the data communications transmitter circuitry and data communications receiver circuitry. In some embodiments, the current sinked from the biasing circuitry is sourced by a power supply configured to power the data communications receiver circuitry. The current sinked from the biasing circuitry is then re-used to power the data communications transmitter circuitry. The data communications transmitter circuitry can be operated using less power overall than the prior art by re-using the current first used to bias the transmission line to power the data communications transmitter circuitry. Various embodiments include HDMI transceivers, DVI transceivers, and DisplayPort transceivers.
