The NE5050 is a modem designed for power line, coaxial cable, and twisted-pair communications. It incorporates features to overcome line impulse noise and line impedance modulation. The modem's transmitter includes a Colpitts oscillator, a carrier-on/-off switch, and a line driver, while the receiver features an amplifier, limiter, amplitude detector, and impulse filter. It supports Amplitude Shift Key (ASK) and Frequency Shift Key (FSK) modulation.
