Abstract
A communication device includes a communication port that includes a digital to analog converter (DAC) that may be configured to output for transmission an analog signal that corresponds to a digital input such as link data that is to be transmitted on a physical link. The communication port further includes a control unit coupled to the DAC and may be configured to provide a bias current to the DAC during operation. In addition, the control unit may further be configured to reduce the bias current to the DAC dependent upon a mode of operation of the communication port and whether there is data to transmit.
