Product specification
Terrestrial Digital Sound Decoder (TDSD2)
SAA7282
FEATURES
Full EBU NICAM 728 specification decoder
Microcomputer controlled via I
2
C-bus
Automatic decoding and output configuration depending
upon transmission:
– digital stereo
– digital mono and data
– 2 independent mono signals
On board RAM for de-interleaving and 10 to 14-bit word
expansion
Automatic mute function which silences the digital data
and switches to FM sound (if valid) when error rate
exceeds user definable limit
User mute function (MUTE pin) to enable user to
perform muting to their own software algorithm if
required, or to simply silence the output
4 times over-sampling digital filter
Selectable digital de-emphasis
256 times over-sampling Noise Shapers
Fully integrated 1-bit DACs
Integrated switching networks allowing selection
between NICAM Sound, FM Sound or external
“Daisy-Chain” input
Digital Audio Interface conforming with EBU/IEC 958
I
2
C-bus transceiver enabling a master device to read
– status information
– error count byte
– additional data bits
and write:
– switch control codes
– decoder control
– upper and lower error rate limits.
APPLICATIONS
Television receivers
Video cassette recorders.
GENERAL DESCRIPTION
Performing all digital decoding functions for a NICAM 728
digital stereo sound system, the SAA7282 is a highly
integrated CMOS circuit which only requires a DQPSK
(Differential Quadrature Phase Shift Keying) demodulator
(TDA8732) and minimum external components to achieve
a full NICAM solution.
The device may also be interfaced to other DQPSK
demodulators.
