Fixed Clock Loads (s1/s2)
Determining Average Switching Frequency
To determine the switching frequency for a design, you must
have a detailed understanding of the data input values to the
circuit. The following guidelines are meant to represent
worst-case scenarios so that they can be generally used to
predict the upper limits of power dissipation. These
guidelines are as follows:
