MAX10 IO Buffer output impedance

Hi, I was just wondering whether anyone have idea regarding typical value of MAX10 GPIO's output impedance. Thanks in advance. Best -Taufiq

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.
