XCZU47DR-2FFVE1156 maximum frequency for AC_PDN analysis

Hi Team,

In one of my design i am using Zynq ultrascale device manufacturer part number "XCZU47DR-2FFVE1156". I need to perform the board lelvel decoupling analysis considering the decoupling capacitors in the power plane to meet the PDN within the specified limit. 

Here, i have doubt what is the maximum frequecny level need to select for the AC_PDN analsys. 

 

Thanks,

Vilas Kumar S

Hi

impedance target and frequency range for ADC/DAC is required as below in UG583image.png

For other digital power rails, the cutoff frequency can be roughly upto 10-20Mhz. I think the median range 15Mhz would be good for your design.
