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?
