I am using IOPLL Intel FPGA IP for Aria 10 SoC device. I need a clock of 307.2MHz/30.72MHz with a ref Clock of 10/100MHz . How can I get the exact clock?

With many possible combinations as well, I could get Actual output clock as 307.5M/307.142M/307.189M but not exact value. M,N,C Counter values can be edited only as integer values but not fractional ...

Hi Anamika Bhushan

For Arria 10 device, yup, you can use the fpll under Transceiver PLL. Regarding the fitter issue when you were using the fpll, can you share with us the parameter setting that you are using for the fpll? Or possibly a sample design that you are connecting the fpll?

Thanks.
