Utilizing Renesas’ third generation of market-leading power line communication (PLC) modem solutions, this winning combination illustrates how PLC can be used effectively to transmit/receive voice communication over low-voltage power distribution lines. The microphone and speaker are controlled by an RX65x MCU, which in turn communicates to the CPX3 modem SoC. The ISL8117 is used to convert an unregulated rectified input voltage to produce a 12V bus required for the line driver. The ISL85415 converts 12V to 3.3V to power the RX65x MCU and the CPX3 modem SoC. An ISL9008 LDO is utilized to create a very low noise power rail for the codec. The ISL28430 is a quad op-amp that is used for microphone amplification and output level indication.
