    • A power supply provides digital data coupling for power-line networking. The power supply includes a power supply side digital interface to transmit and receive a digital data passed through a digital coupler to and from a power-line network access circuitry side digital interface of power-line network access circuitry. The power supply further includes a digital-to-analog converter to process digital data into a high-frequency analog data carrier to provide to a power line of a power-line network. An analog-to-digital converter of the power supply converts a high-frequency analog data carrier from the power line into digital data for the power-line network access circuitry. A power-line analog front end of the power supply transmits and receives the high-frequency analog data carrier to and from the power line. Digital data exchanged between the power supply and the network access circuitry may include control signals for a control circuitry of the power supply. Control circuitry of the power supply may handle control of the digital-to-analog converter, the analog-to-digital converter and the analog front end.
    • 电源为电力线网络提供数字数据耦合。 电源包括电源侧数字接口,用于发送和接收通过数字耦合器传送到电力线网络接入电路的电力线网络接入电路侧数字接口的数字数据。 电源还包括数模转换器,用于将数字数据处理成高频模拟数据载体以提供给电力线网络的电力线。 电源的模拟 - 数字转换器将来自电力线的高频模拟数据载体转换成用于电力线路网络接入电路的数字数据。 电源的电源模拟前端向电力线发送和接收高频模拟数据载体。 在电源和网络接入电路之间交换的数字数据可以包括用于电源的控制电路的控制信号。 电源的控制电路可以处理数模转换器,模数转换器和模拟前端的控制。
