摘要： A power budget controller for an Ethernet device is disclosed. The Ethernet device is connected with another Ethernet device through a cable. The power budget controller includes a length estimation unit, a power selection unit and a link monitoring unit. The length estimation unit is utilized for generating a detection signal to the cable and for estimating length of the cable according to a refection waveform of the detection signal. The power selection unit is coupled to the length estimation unit, and utilized for adjusting a transmission power of the Ethernet device according to an estimation result of the cable length. The link monitoring unit is coupled to the power selection unit, and utilized for monitoring a link status of the Ethernet device to determine whether the transmission power is selected correctly.
