NC200A/IC is an encoder (qpsk modulator) for nicam 728 System B/G, D/K and I. The encoder is mainly used in broadcasting networks, but also used for cable TV and in laboratories. The output is a qpsk modulated carrier at intercarrier frequency, locked to the bit-rate.
The NC200A/IC converts analogue stereo sound via A/D conversion of two sound (stereo) channels, transcoding of digital sound signals to nicam format and qpsk modulation. Options include Data and Clock output.
