LVPECL Output Driver Circuit and Termination
To calculate worst case power dissipation into the load, use the following equations, which assume a 50
Ω load and a termination voltage of VDD – 2V.
For Logic HIGH: VOUT = VOH_MAX = VDD_MAX – 1V.
(VDD_MAX – VOH_MAX) = 1V
For Logic LOW: VOUT = VOL_MAX = VDD_MAX – 1.7V.
(VDD_MAX – VOL_MAX) = 1.7V
Pd_H is power dissipation when the output drives HIGH.
Pd_L is power dissipation when the output drives LOW.
Pd_H = {[ VOH_MAX – (VDD_MAX – 2V)] / RL} * (VDD_MAX – VOH_MAX) = {[ 2V – (VDD_MAX – VOH_MAX)] / RL} * (VDD_MAX – VOH_MAX) = [( 2V – 1V) / 50
Ω] *
1V = 20mW.
Pd_L = {[ VOL_MAX – (VDD_MAX – 2V)] / RL} * (VDD_MAX – VOL_MAX) = {[ 2V – (VDD_MAX – VOL_MAX)] / RL} * (VDD_MAX – VOL_MAX) = [( 2V – 1.7V) / 50
Ω] *
1.7V = 10.2mW.
Total Power Dissipation per output pair = Pd_H + Pd_L = 30.2mW
