CML clock

Hi,

In one of my project with Virtex7  I want to use CML crosspoint switch  (ADN4604) to merge all clock signals in one chip and then connect this chip to Virtex CC  and MGT clock pins.  Would that be ok, if I connect CML signals to 1.5V banks where I have ddr3 memory with external termination to VTT (50Ohm resistors from each line to Vtt) ? Can I use somehow internal termination? Is there any other solution to solve this problem?

Thanks,

Stefan
