Question about AD9172 setup

My setup is as folows:

AD9172 Eval board and ADS7-V2EB7

The DAC board has been modified so a external clk can be provided directly to the DAC.

I have attached the vector and cso file I am using.  

In DPG I have JESD Mode 8 in dual link selected.

My question is, why do the link 0 and link 1 never stabilize?
