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 Eng Wei

    I am using Quartus Prime 19.1.0 and Arria 10 SoC Device.

    For PLL IP Selection, Basic Functions -> PLL -> IOPLL Intel FPGA IP as shown in the image attached.

    For Parameter settings for IOPLL, please refer attached image.As per this, I am not getting fractional calculation settings.

    Could you please check these snapshots and revert.

    Thanks and Regards
