I am using hte AD9524 and noticed that the datasheet was revised in Feb. 2013. There are a number of changes including the elimination of PLL2 1.8V pin which is now a no connect. There appears to be a number of page number references that are incorrect under the 2/13 revision. Without having to go through the entire datasheet, are there any changes I would have to make to my current design besides removing the 1.8V supply to pin 42. Also, has the simulation model for it been updated as well?
