8.1 Overview

THVD8000 enables power line communication using RS-485 physical layer signaling. An integrated OOK modulator enables RS-485 data to be directly coupled onto existing power cables via series capacitors without any updates to the MCU or the controller. The THVD8000 receiver extracts the data from the power cables through series capacitors by using a precise bandpass filter and a demodulator.
