Please help me to adjust Fclk frequency and LC tank
Fif=12.8 MHz, Flo=10 MHz, Fref=26 MHz
I want to get Fclk/8=2.8 MHz on the internal synthezier, so I need Fclk=22.4 MHz.
According to datasheet I need to change register CKN CKR
Also I need to adjust LC tank and I don't understand how to calculate it.
According to page 21 Fosc ...
Also according to page 23
Should I follow to the relation on page 23?
On the EVAL BOARD there is C22=22pF, C56 not installed, L3=1.2uH. It seems to be working with Fclk=18 MHz, but Fclk=22.4MHz doesn't work.
How can I calculate desired Fclk? What should I change on the evaluation board? Please help me. Thank you.
