3. Calculations and Equations.
LVPECL output driver circuit and termination are shown in Figure 6.

voltage of V
Pd_H is power dissipation when the output drives high.
Pd_L is the power dissipation when the output drives low.
Pd_H = [(V
[(2V - 0.935V)/50 ] * 0.935V = 19.92mW
Pd_L = [(V
[(2V - 1.67V)/50 ] * 1.67V = 11.02mW
Total Power Dissipation per output pair = Pd_H + Pd_L = 30.94mW
