I have some questions about AD9525.
(1) In the page 8 of the datasheet , table 12 give the "clock output absolute time jitter". What does it mean? Does this jitter include the performance of the external VCO?
(2) Is there a device that is in the same performance as AD9525 but without the clock distribution function? A single jitter cleaner with one output satisfy my requirement.
(3)Compared with AD9557, the performance of AD9525 improve a lot. Why the phase noise of AD9525 is much better than AD9557?
