LM1893 Overview
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) munication 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...
