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.
