Description

This reference design interfaces an AFE031 Powerline Communications Analog Front End with a C2000 MCU to send and receive data over a wired coupled interface using frequency shift keying (FSK). The design demonstrates the SunSpec standard protocol transmitting the specific 33-bit word packet using FSK (fM: 131.25 kHz and fS: 143.75 kHz). The purpose is to provide a keepalive signal with an integrated system solution that communicates from the solar inverter to the photovoltaic (PV) module.

Features
  • Integrated powerline driver
  • Programmable Tx/Rx Filters and Tx/Rx Gain Control
  • Preprogrammed open source example code for SunSpec protocol
  • High-Resolution PWM
  • Supports EN50065 CENELEC bands A,B,C,D
  • Supports FSK, SFSK, and OFDM
