AD9523-1 PLL2 not locking (DAQ2 + ZC706)

Hi Guys,


I have a custom design based off of the FMCDAQ2 card with the ZC706 board (using HDL 2016_r2 and Linux 2016_R2). The only difference is that OSC_IN going to the AD9523-1 is coming from a 200 MHz VCXO oscillator. 


In my device tree I have changed these lines:

adi,vcxo-freq = <200000000>;

adi,pll2-ndiv-a-cnt = <3>;

adi,pll2-ndiv-b-cnt = <3>;


Is there anything else that needs to be changed?
