Total device C
for multiple (m) outputs switching and (n) LE inputs switching = [m * C
(each output)] + [n * C
(each LE)].
C
(each output) is the C
pd
for each data bit (input and output circuitry) when it operates at 10 MHz (Note: the LE is operating at
20 MHz in this test, but its I
component has been subtracted).
C
pd
(each LE) is the C
pd
for the clock circuitry only when it operates at 20 MHz.
