What is the slew rate and drive strength of LVDCI I/O?
The slew rate attribute (FAST/SLOW) is not used with DCI.
IBIS simulation will show what the resulting slew rate looks like in your actual environment. Slew rate is a lesser issue when the line is matched. It is still an issue with crosstalk and ground bounce; however, you will find that the slew rate is slower in the DCI cases, making these issues less severe.
Drive strength is automatically resolved, so the impedance is matched.
