SAA7282 - NXP

SAA7282 Terrestrial Digital Sound Decoder TDSD2

– 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. SAA7282 Performing all digital decoding functions for a NICAM 728 digital stereo sound system, the SAA7282 is a highly integrated CMOS circuit which only requires .

Features

• Full EBU NICAM 728 specification decoder
• Microcomputer controlled via I2C-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 d.
