After looking at the Avalon data sheet I don't see how to get the clock frequency above 999mhz and satisfy all 3 equations.
Were you able to decipher the data sheet and set the core clock frequency at 1000mhz or above.
If so what values did you use for F,R & OD.
Thanks for any help you can provide to understand this.
You can see what values are used, when you look at this function in the firmware:
https://github.com/formtapez/avalon/blob/master/firmware/Klondike.X/klondike.c#L307The newest datasheet shows slightly other formulas, i didnt got it to work that way, still using the formulas from the older datasheet, works fine.
