We are using 10M08DCU324I7G FPGA in our design. Kindly let me know the what is minimum and maximum frequency of external oscillator input frequency
What is the part number of your external oscillator? you can check from that particular external oscillator's datasheet about the supported input frequency.
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.
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.
