Data Sheet

The MC44C401L Multi-Channel Television Sound (MTS) Stereo

Encoder is the industry’s first, single-chip, CMOS implementation

of a Broadcast Television Systems Committee

(BTSC)-compatible stereo encoder.

The MC44C401L 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 MC44C401L 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 MC44C401L 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 MC44C401L 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.
