THVD8000T 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 allows power delivery and data communication to share a common pair of wires, resulting in a reduction of the system cost.

A pin programmable interface simplifies the system design. The carrier frequency can be adjusted by changing an external resistor on the F_SET pin. A broad range of carrier frequencies gives the system designer the flexibility to choose the external inductors and capacitors. OOK modulation also operates with immunity to data polarity for ease of system installations.

THVD8000EVM — THVD8000 evaluation module with RS-485 over power bus function

This evaluation module EVM is used to evaluate the THVD8000. The RS-485 over power bus functionality can be implemented by connecting Vcc/GND and Vbb/GNB separately. Depending on the applicaiton, different OOK carrier frequency can be selected by switches. All logic signals are available through (...)
