摘要： An electronic apparatus is provided. The electronic apparatus includes a serial advanced technology attachment (SATA) physical layer, a clock generator and a control unit. The SATA physical layer is configured to provide connection with an SATA device and perform data transmission with the SATA device is performed at a first clock frequency. The clock generator is configured to provide a clock signal having the first clock frequency to the SATA physical layer. When at least one specific event is detected by the control unit, the control unit controls the clock generator to provide the clock signal having a second clock frequency to the SATA physical layer, so that the SATA physical layer performs data transmission with the SATA device at the second clock frequency. The second clock frequency is lower than the first clock frequency.
