3. Calculations and Equations.
The purpose of this section is to derive the power dissipated into the load.
LVPECL output driver circuit and termination are shown in Figure 3.
T
o calculate worst case power dissipation into the load, use the following equations which assume a 50
load, and a termination
voltage of V
CC
- 2V.
For logic high, V
OUT
= V
OH_MAX
=
V
CC_MAX

1.0V
For logic low, V
OUT
= V
OL_MAX
=
V
CC_MAX
– 1.7V
(V

- V
OL_MAX
) =
1.7V
Pd_H is power dissipation when the output drives high.
Pd_L is the power dissipation when the output drives low.
Pd_H = [(V
