9 years agoThe clock frequency can be anything up to the maximum specified in the datasheet - in your case 402MHz (providing an appropriate clock network is used).
Drive the clock into any of the 'CLKxx' pins, listed in the 'Optional Function(s)' column, in the 10m02sc device pinout (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/dp/max-10/10m02sc.pdf). Cheers, Alex
