Product specification
Terrestrial Digital Sound Decoder (TDSD2)
Features
- Full EBU NICAM 728 specification decoder
- Microputer 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 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
- I2C-bus transceiver enabling a master device to read
