Complete audio player solutions
Two solutions are offered, illustrated in Figure 89 and Figure 90.
Figure 89 shows storage media to audio DAC/amplifier streaming using a software Codec.
This solution implements an audio crystal to provide audio class I²S accuracy on the master
clock (0.5% error maximum, see the Serial peripheral interface section in the reference
manual for details).
