R9A06G061 is ideal for both AC and DC power line communication. These two block diagrams show a system example for each AC and DC power line application. In the case for the DC line, a compact communication module can be configured using the following Renesas products: PLC modem R9A06G061, line DC/DC regulator, and host MCU. In the case for the AC line, in addition to the products stated in the DC line, Renesas can provide the line driver ISL15102 and an AC/DC convertor. A zero-crossing detection circuit using a Renesas photocoupler can also be added.
