We are designing a PCB that have AD9912 and AD9854 ICs.

The bring up of both these ICs were success, thanks for the support from ADI.

But now we have to synchronize the AD9912 and AD9854.

I have found another article in ez AD9912 Sychronization . But i have AD9854 and AD9912 in different boards.

So the clock driver is not an ideal solution due to routing problems and CMOS levels of AD9854 and AD9912 is different.

We are going to use both the DDS in 250MHZ clock with different oscillators.

Please give me a solution
