Typical DVD5.1 channel audio DA converter circuit

Shown is a typical DVD 5.1-channel audio D/A converter circuit, and the CS4360 chip is a D/A converter. As can be seen from the figure
, the digital audio signals (SDIN1-SDIN4), digital clock signals (SCLK1, SCLK2)
and digital separation clock (LRCK1, LRCK2) signals sent from the digital audio signal decoding circuit are sent to the D/A converter (CS4360 ), perform D/A conversion mode control, amplification
and other processing, and then output 5.1- channel (6-channel surround sound) analog audio signals to the post-stage circuit .
