I am working with the AD9957 eval board and am currently having a problem getting the frequency to lock. Modified the board to use the 25 MHz Crystal.I did use the simulations software which modeled that the frequency should be locking. Here are some screen shots that should be enough to see how I set everything up.

 

Thanks for any help in advance,
