Clock jitter in ADAU1701

Hi,

 

I'm trying to understand if the performance of the ADUA1701 can be improved by using better clocks.

 

Is it possible that the overall audio performance of the ADAU1701 can be improved by supplying an external high performance clock with low jitter instead of using the internal oscillator with a std X-tal?

 

Further on, there is a PLL that generates the internal clock for the DSP. Does the clock for the ADC and DAC come from that PLL or is it from the master clock (12.288 MHz) which, most likely, has lower jitter? If possible, please describe the clocking scheme in the 1701 device.

 

Regards,

 

Mats
