Figure 14. Audio Mode with external Slave Audio Device

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.
