    Hi Chuang,

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

    Thank You

    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
