Transceiver and operation method of the same
The present invention provides a transceiver. The transistor is coupled to a transmission line. The transceiver includes a variable resistor set, a transmitter module, a receiver module, and a digital signal processor. The transmitter module has an output terminal coupled to the variable resistor set and the transmission line. The transmitter module includes a first digital-to-analog converter configured to output an emission current. The receiver module has an input terminal coupled to the transmitter module and the transmission line. When the emission current is fed into the transmission line, a far-end echo is fed into the receiver module. An amplitude of the far-end echo is associated with a resistance value of the transmission line. The digital signal processor adjusts a current value of the emission current from a first default current value to a second default current value based on the amplitude of the far-end echo.
