Overview

Description

Power Line Communication (PLC) is a communication method that uses power lines as the medium, so it is possible to build a system quickly at low cost. Using this method, communication data can be propagated through AC or DC power lines. For example, building automation can be realized using existing AC power lines in the building. Alternatively, DC power lines can be used for communication between devices, reducing device harnesses.

Renesas provides a narrow-band PLC modem IC, R9A06G061, which enables high-speed communication over 1Mbps and stable long-distance communication over 1km for peer-to-peer networks.

System Benefits​:

  • The PLC unit can be configured using Renesas products, including the R9A06G061 PLC modem, line driver, and AC/DC and DC/DC regulators. For a DC line, the PLC unit can be configured in a small size of about 3cm square. The PLC unit actual schematics, BOM lists and Gerber data are also ready.
  • Evaluation boards optimized for AC lines and DC lines are available. A "Performance Test Tool" and sample application software are available which run on the evaluation board. Customers can immediately develop and evaluate a PLC system. Renesas also prepares board schematics, BOM lists and PCB layout guides to support customer development.

Hi-Speed and Long Distance Power Line Communication Unit for DC Line

This video demonstrates the simplicity of LED lighting controlled via power line communication using the R9A06G061 NB-PLC Modem. R9A06G061 is a narrow-band power line communication modem IC that consists of an analog front-end (AFE), DSP and MCU, which enables high-speed and stable long-distance communication peer-to-peer networks. Especially, R9A06G061 has improved direct drive capability to expand its use in DC power supply system applications.
