Hi Rysc

The PLL clock switchover seems to be suitable for my problem. As for Max10 device, the datasheet says that it has the "switchover" feature, however when looking in Qsys ALTPLL-IP for this "switchover" option, I cannot select/active this option as well as "enhanced pll" option in "general" tab. As far as I understand, the "switchover" can only be used in "enhanced pll" type, but the ALTPLL Wizard automatically selects "select the pll type automatically" and does not let me to select PLL type manually.
