Connecting CML Driver output to PLLOSC on AD9956_VCO/PCBZ

I need to connect the diferential output DUT DRV and DUT DRVB of the Evaluation Board AD9956_VCO/PCBZ to the single ended input  DUT OSC IN of the same Evaluation Board. Which is the best way to do it? I think in some options, but i´m not sure which one could work, for example:

1- Adding DUT DRV and DUT DRVB with a signal combiner with 180º between each input.

2- Connecting a load of 50 ohms to DUT DRVB and connecting DUT DRV directly to DUT OSC IN.


If you have some suggestion I really appreciate it.


Thanks in advanced.
