A bridging device with power-saving function includes first and second interfaces, first and second physical layer processing devices, and a controller. The first interface is utilized for coupling a first external device complying with the first interface. The first external device receives a device request signal, and accordingly sends back a device response signal through the first physical layer processing device. The second interface is utilized for coupling a second external device complying with the second interface. The controller is coupled between the first and the second physical layer processing device for transmitting the device request signal with the predetermined frequency to the first physical layer processing device in order to receive the device response signal. When the controller does not receive the device response signal, the controller turns the second physical layer processing device off.
