Freescale Semiconductor  
Technical Data  
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.  
MC44C402  
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.
