New ContributorThank you for the answer.
But I still don't understand the benefit of using 1,8V LVCMOS if, according to the datasheet, the maximum Altera is guaranteeing is 200 MHz for both standards: "I/Os using general-purpose I/O standards such as 3.3-, 3.0-, 2.5-, 1.8-, or 1.5-LVTTL/LVCMOS are capable of a typical 200 MHz interfacing frequency with a 10 pF load." Maybe 1,8V standard would support higher frequencies but if this is still not guaranteed by the manufacturer, the limit is still 200 MHz.

Regular ContributorHi Mabel,
Let's use 200MHz as the limit since it has been mentioned in datasheet.
I think if using higher frequency, there might be some difficulty to meet timing.
