For a further description of the PL485 device see the corresponding PL485 Datasheet .
The PL485 requires an external circuit to couple the PLC signal to the transmission line. Microchip provides highly
efficient and reduced BOM reference designs for the different coupling options, targeting common configurations in
all PLC bands (<500 kHz) complying with existing regulations and PLC communication protocols.
