GENERAL DESCRIPTION
Philips Semiconductors have pushed the boundaries of
Stereo Sound further with this addition to the successful
Terrestrial Digital Sound Decoder family. The SAA7284
device is an application specific version of the existing
SAA7283, with guaranteed improved specification on
selected parameters, enabling comparable RF
performance in conventional intercarrier PLL-IF systems,
to that of the SAA7283 in QSS systems.
The SAA7284 takes, as input, a second IF (intercarrier)
Terrestrial TV PAL signal, and performs all the Differential
Quadrature Phase Shift Keying (DQPSK) demodulation,
digital decoding and digital-to-analog conversion
necessary to produce a complete NICAM receiver on a
single integrated circuit.
The demodulator function includes integrated baseband
filters for pulse shaping and unwanted signal rejection,
automatic gain control, a low jitter integrated VCO, digital
monostables for precise data sampling points and a
multi-standard controller to enable automatic locking to
either a PAL system I or PAL system BGH input signal.
The decoder function performs the descrambling,
de-interleaving and reformatting operations required to
recover the original data words.
The data words are processed through a stereo digital
filter, digital de-emphasis network, second order noise
shaper and 256 times oversampling Bitstream audio DAC.
