DESCRIPTION

The TDA8204B performs two main functions, first

one is NICAM decoding, second one is audio signal

recovery (DAC) combined with audio signal switch-

ing (Matrix). An I

2S output is provided for digital

audio when required and all functions of both the

TDA8204B and the TDA8205 are accessed via an

on-chip I

2C bus interface. The I2S interface can be

used as an input for converting to analog some I

2S

digital sound.
