Control of the level of the signal produced by a transceiver coupled to a power distribution line

摘要

A method for controlling the level of a signal produced by a transceiver of digital data coupled to a power distribution line during a transmission phase is provided. The level of the signal output by the transceiver is regulated by comparing the current level of the output signal with a predetermined minimum threshold and a predetermined maximum threshold, reducing the current level when the maximum threshold is exceeded by reducing the gain, and switching to a voltage mode control of the output signal when the current level of the output signal becomes lower than the minimum threshold.
