Abstract
The present invention provides a driving system operating in a first or second modes. The driving system includes first and second resistance adjusting circuits, a divider, a controller and a driver. The divider divides a second resistance adjusting signal generated by the second resistance adjusting circuit by a standard value to generate a first control signal. The controller receives the first control signal and generates a second control signal. When the driving system operates in the first mode, the driver receives the second control signal, according to the second control signal, the driver adjusts an output impedance of itself and adjusts equalization amplitude of a first differential output signal generated by itself. When the driving system operates in the second mode, the driver generates a second differential output signal and adjusts the output impedance according to a first resistance adjusting signal generated by the first resistance adjusting circuit.
