NXP Semiconductors SAA7282
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.| Part No. | SAA7282 |

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 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 – status information QUICK REFERENCE DATA SYMBOL VDD IDD fXTAL Tamb supply current crystal frequency operating ambient temperature PARAMETER positive supply voltage 4.5 − − 0 MIN.
