GENERAL DESCRIPTION
The SAA7283 is a NICAM receiver solution, developing
the well established high quality Terrestrial Digital Sound
decoder family from Philips Semiconductors.
This innovative IC with analog front-end, offers more
impressive features and flexibility with minimum external
circuitry.
The SAA7283 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
monostable 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
(including French NICAM L system).
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.
The SAA7283 then provides a switching output buffer for
selecting between FM, NICAM and daisy-chain inputs, and
a programmable level attenuation matrix for matching
levels of the FM and NICAM audio sources at the output of
the device. An additional feature is the inclusion of a Digital
Audio Interface (DAI) output IEC 958, which may be
disabled if required.
