applications
2 Applications
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 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 F_SET 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.
