hello, tell me, I have a question about DE1-SoC. Is it possible to use custom GPIOs as clock output sources? and how? I need a frequency of 13 Mhz. There is also a serious question about the stabilit...

Super ContributorHi,
you can send PLL generated clock to GPIO output. Quartus generates a warning that you don't use dedicated clock output, which should be ignored. Generated clock has stability of DE1-SoC 25 MHz crystal oscillator with some additional jitter.

New ContributorThank you for responding. The question now is, do all GPIO pins fit the clock source? If not all, which one is better to use? Now I need 60 Mhz from this contact
