3. Calculations and Equations.
The purpose of this section is to derive the power dissipated into the load.
HSTL output driver circuit and termination are shown in
Figure 1.

o calculate worst case power dissipation into the load, use the following equations which assume a 50

load.
Pd_H is power dissipation when the output drives high.
Pd_L is the power dissipation when the output drives low.
