Abstract:
1. A method in a physical layer device for controlling radiated emissions in a data network application in an automotive vehicle, comprising: retrieving, by a control module in said physical layer device, configuration parameters from a control register; configuring, by said control module, a transmit symbol rate and a transmit power level of a modulation module in said physical layer device based on said retrieved configuration parameters; and configuring, by said control module, a wave shaping function implemented by a wave shaping module in said physical layer device based on said retrieved configuration parameters, said wave shaping module applying said configured wave shaping function to a modulated signal generated by said modulation module at said configured transmit symbol rate and said configured transmit power level, wherein said configured wave shaping function as applied to said modulated signal reduces signal emissions when said wave shaped modulated signal is transmitted in a communication cable in said automotive vehicle.
