how many is the current strength of LVDS io in Cyclone IV E device?

[BQi]

we find the program current strength value in handbook, but many other different io standard have the value, even BLVDS, but we can not find the value of LVDS. it is blank.

we need the value to design hot socketing

Hi Chuang,

LVDS for Cylone IV E has only 2 current drive strength. Which are maximum and minimum only.

Thank You

What is the value? 2mA? 8mA?

Hi Chuang Qi,

Apologize for the late as i have just got the information from internal discussion. Apologize that programmable current drive strength is not available for LVDS.

Thank You
