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 5.
T
o calculate worst case power dissipation into the load, use the following equations which assume a 50
Ω
load, and a termination
voltage of V
CC
- 2V.
For logic high, V
OUT

For logic low, V

OL_MAX
=
V
CC_MAX
– 1.78V

1.78V
Pd_H is power dissipation when the output drives high.
Pd_L is the power dissipation when the output drives low.
