External Input clock frequency of 10M08DCU324I7G - External Input clock frequency of 10M08DCU324I7G We are using 10M08DCU324I7G FPGA in our design. Kindly let me know the what is minimum and maximum frequency of external oscillator input frequency Replies: Re: External Input clock frequency of 10M08DCU324I7G Hi, One more clarification, If we are not use PLL in our application, Can we use 4MHz external crystal? Whether 10M08DCU324I7G will support for 4MHz? Replies: Re: External Input clock frequency of 10M08DCU324I7G I’m glad that your question has been addressed, I now transition this thread to community support. If you have a new question, feel free to open a new thread to get support from Intel experts. Otherwise, the community users will continue to help you on this thread. Thank you.

Regards, Aqid Ayman Replies: Re: External Input clock frequency of 10M08DCU324I7G Hi, In that link, PLL Input clock frequency mentioned as 5MHz to 472.5MHz. So we need to select the external crystal oscillator to be selected in that range, since we cannot drive PLL with internal oscillator. Whether my understanding is correct or not? I have attached the snapshot from MAX10 handbook for reference.
