I plan to use the digital clock out in divide by two mode, 150MHz input 75MHz output.
How much jitter does the chip add to this signal compared to the jitter in ADC clock input?
THe DCO is not intended as a precision clock source, but rather as an aid to capturing the data into an external register. (As described on Page 22 of the Rev 0 Datasheet). We therefore do not specify additive jitter for the DCO.
If what you are trying to do is create a synchronous low jitter clock source, an option whould be to use one of our Clock Generation and Distribution products.We offer free ADIsimClock software to assist in designing and evaluating your clock chain needs.
