I am working on a design for the University of Minnesota for increasing MRI scanner resolution. I have not had to use jitter attenuating devices in the past Apparently, jitter on clocks really affects ADC resolution when using a external clock (I am using the CS5560).
I am considering using the part shown in the link below for jitter attenuation.

I plan to use 16MHz crystal for the device.
First off - I don't understand why ICLK is needed. What is this, why is it there, and how do I decide how to use it appropriately? It seems that this is basic knowledge that I should understand because a kindergarten explanation is not given. I cant even tell if ICLK1 and ICLK2 are needed.
Second - I do not understand loop bandwidth and how this relates to my crystal frequency? For instance, page 4 shows how to set the loop bandwidth. I do not understand how this relates to my clock frequency? Could someone explain this?
Thanks for the help.
