MCLKI with I2S in ADAU1701

Hello,

 

It's been discussed elsewhere but still want to confirm:Is it really required to synchronize MCLK with audio source when feeding I2S stream to ADAU1701 from I2S master? I2S stream gets synchronized from BCLK; isn't that enough?

 

I'm asking because in the system under development the BT module (master) doesn't have any other clock output than BCLK and WORD CLOCK, and programming some BT GPIO to generate "MCLK" would require to develop FW for BT module with extra cost.

 

Thanks,

Ari
