RS-485 transceiver with OOK modulation for power line communication

THVD8010 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 significant 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 FSET pin. A broad range of carrier frequencies gives

the system designer the flexibility to choose the external

inductors and capacitors. In addition, OOK modulation

operates with immunity to data polarity for ease of system

installations.
