I was able to seperate the above frequencies into smaller incremental steps, but I have no idea how to calculate the "reg. value" or the "ideal delay" for them. Anyone with a little more know-how than myself willing to help out? I know a few other people in this thread were looking for something like this as well, and any help at all would be appreciated. Thanks!
Adjusting the S1 formula based on S3 ASIC spec I was able to get following register values (and timeout). Use the settings below at your own risk!

JakeTri -- I would like to thank you for your work, I know the request wasn't mine, but I was wondering about this the same as la7eralus. I'm interested in how you calculated those Reg. values. I would like to break this down one more level and be able to find the nitch between 250 and 243.75. I looked at the Reg. values and attempted to convert from HEX...but that didn't look even close to right. So...i'm interested in how you calculated them. If you could explain, or point me to some documentation that explains it...i would be grateful. I have done a few Google searches...but found zip. Any direction you could give would be appreciated.
