MTS Stereo Encoder
The MC44C402 Multi-Channel Television Sound (MTS) Stereo Encoder is
based on the industry’s first, single-chip, CMOS implementation of a Broadcast
Television Systems Committee (BTSC)-compatible stereo encoder, the
MC44C400.
The MC44C402 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 MC44C402 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 MC44C402 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 MC44C402 is designed to output
this signal to a Freescale RF modulator, which in turn produces a stereo encoded
RF channel for use with any BTSC stereo television receiver.
Features
Integrated A/D converter input and D/A converter output circuitry
CEX digital audio processing encodes and transports stereo signals
Surround sound and Macrovision compatible
Extended low frequency response (The MC44C402 frequency response
extends below 25 Hz)
Simple passive interface to Freescale’s MC44BS373/4 (UHF/VHF) and
MC44BC375 (VHF) modulators
Preservation of original surround sound fidelity
System performance not impacted by copy protection technologies
Low system component count, small board size, and significantly low overall
system cost
No manual alignment of filters or phase controls
