Carrier-current systems use the power mains to transfer information
between remote locations. This bipolar carriercurrent
chip performs as a power line interface for half-duplex
(bi-directional) communication of serial bit streams of
virtually any coding. In transmission, a sinusoidal carrier is
FSK modulated and impressed on most any power line via a
rugged on-chip driver. In reception, a PLL-based demodulator
and impulse noise filter combine to give maximum range.
A complete system may consist of the LM1893, a COPSTM
controller, and discrete components.
