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…
Hi petre san,
Thank you for reply!
AD9523-1 datasheet register map & Table.20
Minimum value is 0 pF.
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.
So I do not understand the problem
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?
Please continue to use the data sheet as the reference.
Thank you for useful information !
