3. Calculations and Equations.
The purpose of this section is to calculate power dissipation on the LVPECL output pair.
LVPECL output driver circuit and termination are shown in Figure 6.
T
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 – 0.9V)/50 ] * 0.9V = 19.8mW
Pd_L = [(V
[(2V – 1.7V)/50 ] * 1.7V = 10.2mW
Total Power Dissipation per output pair = Pd_H + Pd_L = 30mW
