So I initialize my LMX2594 to one clock rate and set up my ADCs/DACs and they all work fine.
However, after I have already initialized it and I want to reconfigure I call LMX2594ClockConfig() again with a new rate, and now when I set my mixer settings they are mistuned (by a ratio of the first clock rate to the second).
Do I have to reset all of my tiles (PG269, page 106-107) in order for the power up sequence to pass the new clock information to the tiles?

Usually we need shutdown and startup the tile if clock setting changed.
Have you ever tried shutdown/startup the tile and can this help make your new setting works fine? I am wondering if this cannot help the new rate work fine that might have some additional settings needed.

Sorry for the delayed reply. I was on Vacation for a week.
Have you tried API function XRFdc_DynamicPLLConfig after you change the LMK2594 output clock with a new frequency?
You can set your new reference clock frequency and sampling clock frequncy with this function and then reset the whole tile.
