Hello rejeesh,

i came from Jinan university of China, now we are working with zc706 and DAQ2. i am quite confused about the crystal clock input of the ad9523 in DAQ2, please help.

1,From the following URL, there is the 125Mhz crystal provided to ad9523.

2,But in the following URL,there is "Crystal generates a fixed clock frequency of 250MHz."

On the PCB board, it's 125Mhz crystal. So Is the clock provided to FMC zc706 still 500Mhz? of half of that?
