AD9508 as a LVDS clock distributer

Hello

I need an urgently answer

I have a FPGA and a DAC.

 

The FPGA has its clock and is working normally and it will send a command to activate the below XO.

 

(low jitter LVDS XO)---> AD9508---> DAC

 

if I want to send the digital data to the DAC, I need a clock feedback from above clock generator. how should I sync the DAC with the FPGA? I mean if want to have a feedback clock, there is delay.

(I read the AD9805's datasheet but I'm puzzled with the SYNQ pin and other pins...)

could you please help me?

 

Best Regards
