TDA8732 Description
TDA8732 The NIDEM is a dedicated device providing a DQPSK (Differential Quadrature Phase Shift Keying) demodulator for a NICAM-728 system. The device interfaces with NICAM-728 decoders and provides data synchronized to a 728 kHz clock (either supplied externally or by the on-board clock). The device consists of a costas loop quadrature demodulator, a bit-rate clock recovery and differential decoder with...
