About the programmable value of Cpole1, PLL2 is difference from datasheet and ADIsimCLK.
Which is true ?
Minimum value is 0 (open or short ?) or 1 pF ?
AD9523-1 datasheet register map
AD9523-1 ADIsimCLK parameter
if I understand correctly, the difference is that the data sheet repeats the 24pF option twice while the ADIsimCLK does not.
The data sheet mentions these values in Table 20:
So I do not understand the problem
Hi petre san,
Thank you for reply!
AD9523-1 datasheet register map & Table.20
Minimum value is 0 pF.
Minimum value is 1 pF.
Which is true, 0 or 1 pF ?
If 0 pF is true, it means open or short circuits ?
Can you comment regarding this matter or from anyone?
the 0pF selection in the data sheet means that no capacitor is used in the Cpole1, so it means an open circuit.
I do not know why ADIsimCLK has a selection of 1pF that is not in the data sheet.
Please continue to use the data sheet as the reference.
Thank you for useful information !
