Hi Chuang,

 

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

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
