MAX10 IO Buffer output impedance

Best answer is 'it depends'. What I/O type are you using? Do you enable the OCT (on chip termination) or not? There is not a simple answer to that question.

I am using 3.0V LVCMOS with max current output and fastest slew rate. No, I don't enable OCT.

Thanks ak6dn btw for replying.

Well, in the Max10 datasheet I/O electrical specs (have you read that?) 3.3V LVCMOS is rated at Vol of 0.2V at Iol of 2mA; this is 100ohm worst case, typical will be lower.

3.0V LVCMOS has a (wierd? questionable?) spec of Vol of 0.2V at Iol of 0.1mA (is this real or a typo?). If real this would be 2000ohm worst case, typical will be lower.
