CALCULATIONS AND EQUATIONS
To calculate worst case power dissipation into the load, use the following equations, which assume a 50Ω load and a termination voltage of V
For Logic HIGH: V
(V
For Logic LOW: V
(V
Pd_H is power dissipation when the output drives HIGH.
Pd_L is power dissipation when the output drives LOW.
Pd_H = {[ V
1V = 20mW.
Pd_L = {[ V
1.7V = 10.2mW.
Total Power Dissipation per output pair = Pd_H + Pd_L = 30.2mW
