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 I²S output is provided for digital
audio when required and all functions of both the
TDA8204B and the TDA8205 are accessed via an
on-chip I²C bus interface. The I²S interface can be
used as an input for converting to analog some I²S
digital sound.
