Interfacing 4 ADCs and 4 DACs with ADAU145X

Hello,

I am starting a new project that will in effect be a 8In 8Out Audio Processor.

Unless there is something new on the horizon with built-in CODEC, I have shortlisted the ADAU145X processor, PCM1860 ADC and PCM5100 DAC to do the job.

 

I want to interface 4 ADCs and 4 DACs to the ADAU145X processor.

Can I use only one clock pair say LRCLK_IN0 and BCLK_IN0 to clock all the 4 ADCs and similarly LRCLK_OUT0 and BCLK_OUT0 to clock all the 4 DACs or is it mandatory to use the corresponding clock pair with the serial data line?

 

Kindly let me know if you need any further information from my side to answer my query.

Thanks!!
