LM1893 Product details

Description

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 th.

Features

Y Y Y Y Y Y Y Y Y Y Noise resistant FSK modulation User-selected impulse noise filtering Up to 4 8 kBaud data transmission rate Strings of 0’s or 1’s in data allowed Sinusoidal line drive for low RFI Energy management systems Home convenience control Inter-office communication Appliance control Fire alarm systems Security systems Telemetry Computer terminal interface Typical Application TL H 6750.
