Hello,

Thank you for your clarification on Q1. We do not specify the value for Fast or Slow slew rate because it largely depends on the load that the signal is driving to. However, you could use the IBIS model to do signal integrity simulation to verify the behavior of different slew rate to your setup. This will help you to select the optimal slew rate for your setup. Generally, faster slew rate you can have higher fmax, but SI might degrade due to reflection. Slower slew rate you get lesser fmax but less reflection issue.

Regards,
