RS-485 transceiver for power line communication

02-07-2020 | Texas Instruments | Semiconductors

Texas Instruments THVD8000 is an RS-485 transceiver with on-off keying (OOK) modulation and demodulation built-in for power line communication. Modulating data onto existing power lines enables power delivery and data communication to share a common pair of wires, ending in a notable decrease in the system cost.

A pin programmable interface simplifies the system design. The carrier frequency is able to be adjusted by modifying an external resistor on the F_SET pin. A wide variety of carrier frequencies provides the system designer with the versatility to select the external inductors and capacitors. Also, OOK modulation functions with immunity to data polarity for ease of system installations.
