Transmission of charging signals on a data transmission path |
摘要 |
An apparatus for transmitting charging signals on a data transmission path having a line impedance includes a driver device for setting a line voltage level that corresponds to the line impedance. The driver device is configured to provide, in response to a driver input voltage level, a driver output current and a driver output voltage level. A current detection unit provides a current signal indicative of the driver output current and a current signal matching unit receives the current signal from the current detection unit and adjusts a level of the current signal for further processing by a filter device and by a regulation device. A matching filter unit then matches the driver device to a data transmission path unit.
