The 2 stereo channel serial audio interface of the TDA7580 chip allows a very flexible
application in which external audio source/sinks can be connected.
The example shows an external CD player digital output giving the main Fs audio rate of the
whole system. This rate is also the one of the external DACs and an ADC, being configured
as slave.
