PCM1794 DAC and CD pro2 clock

Hi,

There must be an answer to my question in one topic here ( in this case could you give me this link I can't find 🙂 )

I'm building a pcm1794 dac with a cd pro2 mechanism.

The cd pro2 is 8.4672 MHz clocked.
Reading the pcm1794 datasheet shows that it has a system clock detection circuit that automatically senses the frequency at which the system clock is operating so as I have a 16.9344 MHz clock I think it's ok ... ?

My second question is : would it be better having only one clock for the pcm1794 and the cd pro2 ?

Thanks in advance.
