â Total device Cpd for multiple (n) outputs switching and (y) clocks inputs switching = {n * Cpd (each output)} + {y * Cpd (each clock)}.
â¡ Cpd (each output) is the Cpd for each data bit (input and output circuitry) as it operates at 5 MHz (Note: the clock is operating at 10 MHz in this
test, but its ICC component has been subtracted out).
§ Cpd (each clock) is the Cpd for the clock circuitry only as it operates at 10 MHz.
