电力线语音通信

概览

该设计采用瑞萨电子市场领先的第三代电力线通信（PLC）调制解调器技术，通过低压电力线有效地传输语音。 麦克风和扬声器由 MCU 控制，MCU 与 PLC 调制解调器 IC 通信。 同步降压型降压控制器转换一个未稳压的整流输入电压，为线路驱动器产生一个 12V 总线。 此外，一个 500mA 同步降压稳压器将 12V 降至 3.3V，为 MCU 和调制解调器 IC 供电。 LDO 为编解码器生成噪声非常低的电源轨，而四通道运算放大器用于麦克风放大和输出电平指示。

系统优势：

  • 兼容任何 PLC 协议标准，例如 PRIME 1.3.6/1.4 和 G3
  • 低功耗设计确保在紧凑的空间内实现高效率
  • MCU 以低功耗运行频率高达 120MHz，具有高达 2MB 的片上闪存和 640KB 的 RAM
