I am trying to communicate with the AD4350 on the AD9739A-FMC-EBZ.  I am connecting the AD9739A-FMC-EBZ to the LPC connector of the Xilinx ZC706.  I can see my serial signals making it to U1 on the AD9739A-FMC-EBZ but on the output side of U1 the signals are corrupted.  That is, they are very rounded off and the clock is riding on top of a 1 volt signal.  So, the interface doesn't work.


Any suggestions?


Thank you!
