The VCO operating frequency can be determined by using the following relationship:
fvco = frefclk × M
and
fclkout = fvco / O
where, M corresponds to the integer feedback divide value and O corresponds to the value of output divide.
Note: The PLL does not support fractional divider values.
Important: Select the PLL feedback multiplier
value based on the supported VCO frequency range (fvco).
Refer to the Versal AI Core Series Data Sheet: DC and AC Switching Characteristics (DS957) for more information on the operating range of fvco.
Select the output divider (O) based on the required core clock or MCU clock frequency.
