3. Calculations and Equations.
The purpose of this section is to derive the power dissipated into the load.
LVCMOS output driver circuit and termination are shown in Figure 9.
T
o calculate worst case power dissipation into the load, use the following equations which assume a 50
load, and a termination
voltage of V
DD
- 2V.
Pd_H is power dissipation when the output drives high.
Pd_L is the power dissipation when the output drives low.
Pd_H = (V

Pd_L = (V

Pd_H = (1.2V/50
) * (2V - 1.2V) =

Pd_L = (0.4V/50
) * (2V - 0.4V) =
12.8mW
Total Power Dissipation per output pair = Pd_H + Pd_L =
