9 years agoA 25MHz or 50MHz would probably be a better choice than 5MHz; as these frequencies are very common and the devices are readily available.
Multiplication factor would be 10X smaller at 50MHz vs 5MHz, s depending on the characteristics of your 5MHz device you might get better jitter performance at 50MHz. 5MHz is the absolute minimum input frequency to the PLL on a MAX10, so you would be right at the limit of the device capability.
