Abstract
A power-saving network apparatus includes a MAC and a PHY. The PHY includes a transmitter and a receiver. The transmitter executes the operations of: transmitting a data signal to a remote network apparatus according to output packets of the MAC when the transmitter enters a normal state; transmitting an idle signal to the remote network apparatus when the transmitter enters an idle state; transmitting an indication signal to the remote network apparatus to notify it to enter a low power state, wherein the indication signal is different from the idle signal; entering the idle state or the normal state from the low power state in response to at least one of a predetermined period and a transmitting enable signal.
