STM32F7 and I2S CODEC (CS43L22)

I'm working on a new PCB design based on ST32F746 Discovery schematics.

I want to change the CODEC to a cheaper CS43L22 DAC.

Can someone help me make the correct connections to the DAC (MCLK, SCLK, SDIN, LRCK) ?

An F7 schematic with this DAC would be great.....!

CS43L22 is used in the 'F4 DISCO, you can perhaps got inspired there.

However, you might want to consider connecting it to SAI, too.

Btw., CS43L22 is only a DAC, not a CODEC.
