I hope to synchronize 32 pcs AD9912. But when we test with only 2 pcs of
AD9912, the difference of output phase are variable each time after power on. I
disabled the CLK multiplier and provided 1GHz clock external, the update
clocks are also synchronized. How can I synchronize output phase of AD9912?
Multiple AD9912s can be synchronized however there's setup and hold times that
I have started an initial application note that addresses how to synchronize
but again the timing has not been characterized.
Please see the attachment.
