Hi, in my application, I want to use 2pcs of AD9963 on one board to get a Quad channel ADC inputs + Quad Channel DAC outputs, is it possible to sync these two AD9963 by bypassing the DLLs? Drive two 9963's CLK with a CLK distribution chip instead, will this make these two 9963s' 4 ADCs and 4 DACs have no phase differ? 

 

And, will the 2× decimating low-pass filter affect the 4 ADCs' sync? 

 

 

Thanks you! 

 

Frank
