Synchronizing multiple AD9959

I'm building a board with multiple AD9959 and I have a doubt.

If I want the DDSs fully synchronized I don't know if I have to use a REF_CLK equal to the system clock by disabling all the internal PLLs or if I can use a REF_CLK of lower frequency and make use of internal PLL of the different AD9959s?

What is the best solution?
