Nicam-728 Demodulator Nidem

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 parallel-to-serial conversion. The Voltage Controlled Oscillator (VCO) used in the costas loop is achieved with a single-pin crystal Oscillator A second single-pin crystal Oscillator with a divider chain provides signals at 5.824 MHz and at 728 kHz. The NIDEM is suitable for PAL B and G (carrier Oscillator crystal at 11.7 MHz) and PAL I (carrier Oscillator crystal at 13.104 MHz). By NXP Semiconductors
