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 4.
T
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 = (1.4V/50 ) * (3.465V - 1.4V) = 57.82mW
Pd_L = (0.4V/50 ) * (3.465V - 0.4V) = 24.52mW
Total Power Dissipation per output pair = Pd_H + Pd_L = 82.34mW
