Can you provide equations for calculating IP_XO_CLOAD and IP_BIAS_SEL_XO?
I am using a 25MHz crystal with 8pF load capacitance and 100Ω ESR. The traces are very short and copper planes are cut out below the crystal. Routing capacitance should be minimal.
I do not see equations in the data sheet or register map documents.
Also the loop filter settings provided in Table 3 of the data sheet are not labeled the same as the register fields or the selections in TICS Pro. I think I have decoded most of the settings, but I am still missing R3 and C3.
I am trying to get fVCO=2500MHz from fPFD=50MHz.
Thanks for any advice.
