Here’s a sample calculation done for the VGA line rate shown. For any line rate, you can plug the appropriate number in the equations shown here. But you must know the percentage of active times, the total time for both the horizontal and vertical scan, in order to do so. Here, you see the line rate information is plugged directly into the equation for rise/fall time to arrive at the 14.7 nanosecond value. This will then be used to come up with the 24 megahertz for bandwidth in the lower equation and 95 volts per microsecond for slew rate. That’s how the values in the table are tabulated here.
