About a capacitor on loop filter for LRCLK PLL on AD1934

Hello all,

 

I have a question.

 

There is a electrolytic capacitor of 39nF on the circuit on Figure.21 on p.25 of AD1934 data sheet.

 

Can I use the same value of ceramic capacitor instead?

Is there any precaution if I do?

 

I have checked the schematics of AD1938 EVAL board manual. the filter was for MCLK PLL

 

Thank you very much.
