LM1893 LM1893/LM2893 Carrier-Current Transceiver

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 mo.
