The MC44C401 MTS Stereo Encoder is designed for use in set-top boxes, VCRs, DVD players/recorders, game stations, and other applications that are required to output high-quality stereo sound through a single RF coaxial cable. The digital audio processing used in the MC44C401 preserves the full fidelity of surround sound and other audio coding schemes while ensuring overall system performance is not impacted by copy protection technologies. The MC44C401 is engineered to process right and left analog audio signals and baseband composite video to generate a stereophonic composite signal in accordance with BTSC system standards. The MC44C401 is designed to output this signal to a Motorola RF modulator, which in turn produces a stereo encoded RF channel for use with any BTSC stereo television receiver. 1 Features * * * * Integrated A/D input and D/A output circuitry CEXTM digital audio processing encodes and transports stereo signals Surround sound and MacrovisionTM compatible Extended low frequency response (The MC44C401 frequency response extends below 25 Hz) (c) Motorola, Inc., 2004.
