Hi, sorry to keep you waiting.
Arria 10 FPGA has 2 types of PLL : Fractional and Integer PLL.
Fractional PLL is used when you want to generate a uncommon clock frequencies with fractional numbers such as 6.625Mhz, 3.125Mhz etc clock frequency.
Integer PLL is used when you want to generate a common clock frequencies like 10Mhz, 25Mhz, 125Mhz etc.
how to use and set fractional PLL is shown in this link:
https://www.intel.com/content/dam/altera-www/global/ja_JP/pdfs/literature/an/an661.pdf
and this document shows how to calculate Fractional PLL divider value during setup:
while integer PLL is more straight forward setup, this is the documentation of it :
If you are new to PLL in Intel FPGA, I would suggest you to get familiar with integer PLL first, then slowly move to Fractional PLL.
best regards,
Farabi

Hi,
I am Farabi who will support you on this request. Let me check the documentation on the integer/fractional PLL setup information.
I will come back when I have the information you requested asap.
regards,
Farabi
