GENERAL DESCRIPTION
Performing all digital decoding functions for a NICAM 728 digital stereo sound system, the SAA7280 is a CMOS integrated circuit which operates in conjunction with a DQPSK (Differential Quadrature phase Shift Keying) demodulator (TDA8732) and a dual DAC (TDA1543). The device may also be interfaced to other DQPSK demodulators and DACs.
