NICAM 728: Transmission of two-channel digital sound with terrestrial
Intended 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.
Engineered to process analog audio signals to generate a QPSK modulated
signal in compliance with the EN 300 163 standard.
Designed to output this signal to a Freescale RF modulator, which in turn
produces a stereo encoded RF channel for use with any NICAM stereo
television receiver.
Supports B, G, H, I, K1, L system standards
NICAM digital audio processing encodes and transports stereo signals
Integrated A/D converter input and D/A converter output circuitry
Extended low frequency response (below 25 Hz)
Simple passive interface to MC44BS373/4 UHF modulators
Low power consumption - typically < 50 mW
RoHS compliant
Preservation of original surround sound fidelity
Multi standard
Low system component count, small board size and significantly low overall
system cost
No manual alignment of filters or phase controls
e MC44C404 NICAM Stereo Encoder is the industry’s first single-chip
