POWER CONSIDERATIONS
This section provides information on power dissipation and junction temperature for the ICS830521I.
Equations and example calculations are also provided.
1. Power Dissipation.
The total power dissipation for the ICS830521I is the sum of the core power plus the analog power plus the power
dissipated in the load(s).
The following is the power dissipation for V
DD
= 3.3V + 5% = 3.465V, which gives worst case results.

= 18pF * 250MHz * (3.465V)2 = 54.0mW
Total Power Dissipation

Total Power + Power (250MHz)
= 155.93mW + 10.7mW + 54.0mW
=220.6mW
