3. Calculations and Equations.

The purpose of this section is to calculate power dissipation on the IC per HCSL output pair.

HCSL output driver circuit and termination are shown in Figure 4.

Figure 4. HCSL Driver Circuit and Termination

HCSL is a current steering output which sources a maximum of 17mA of current per output. To calculate worst case on-chip power dissipation,

use the following equations which assume a 50

 load to ground.

= (3.6V – 17mA * 50

Total Power Dissipation per output pair = 46.8mW
