We are using AD9517-3 on-chip VCO working at 2048MHz with a 10MHz reference.
Following the ADIsimCLK ("Frecuency Tune Dialog") the VCO tuning voltage
should be around 1.375. But we get 1.68 in some boards and 1.29 in others
In this condition, after a new recalibration the VCO voltage remains the same.
Could you tell us which should be the tuning VCO voltage?
Has the loop filter influence on the calibration process?
