I see that the setup times for 4.5V and 2V are different, but I would like to know what the setup time is for 3.3V, because the setup requirement at 2V is too large for me to use.

Hi Jacky,
You can use linear interpolation for this. For example, I calculated the typical value at 3.3V as 29.4ns using the calculator below:
