Carrier Current Systems LM1893 (Power Line Communication Modem)

Carrier-current systems use the power mains to transfer information between remote locations This bipolar carrier current 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.
The output power easily boosted to 300 kHz carrier frequency choice TTL and MOS compatible digital levels Regulated voltage to power logic Drives all conventional power lines
