High Speed 4-channel DAC

Question asked by mfsd on Jun 1, 2012

I am in the process of component selection for a new design, and I would like to ask your help when selecting the right DAC.

 

The application requires 4 channel DAC to generate frequency chirps between 100 and 500MHz, with an amplitude resolution of >14bit. Furthermore, the channels need to be perfectly synchronized. <100ps between channels.

 

I have been looking into some of Analog's IC, such as the AD9736 and AD9739, but I am not sure how good can I sync the outputs?

Do they have significantly variations from batch to batch concerning Internal delays, etc.?

 

I would really appreciate your suggestions.

 

Thanks,

/M
