The detector is coupled to the receiver, and utilized for detecting a link status of the network device and a link partner to generate a first detecting result. The controller is coupled to the first timer, the transmitter, and the detector, and utilized for determining whether to power down the transmitter according to the first detecting result and the first predetermined time.

Abstract: A network apparatus with power saving capability includes a network block, a cable-connection status detection circuit and a control circuit. The network block is used for providing a network communication function. The cable-connection status detection circuit is used for detecting the cable-connection status between the network block and the link partner to generate a detecting result. The control circuit is coupled between the network block and the cable-connection status detection circuit, and implemented for controlling the network block to switch between a first operation mode and a second operation mode according to the detecting result. The power consumption of the network block operating in the first operation mode is higher than the power consumption of the network block operating in the second operation mode.
