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.
Core and LVDS Output Power Dissipation

* (I

Output Current I
OUT = VDDO_MAX / [2 * (50Ω + ROUT)] = 3.465 / [2 * (50Ω + 15Ω)] = 26.7mA
Power Dissipation on the R
OUT per LVCMOS output
Power (R
OUT) = ROUT * (IOUT)

Ω * (26.7mA)2 = 10.7mW
Dynamic Power Dissipation at 250MHz
Power (250MHz) = C
PD * frequency * (VDD)

= 18pF * 250MHz * (3.465V)2 = 54.0mW
Total Power Dissipation
Total Power
= Power (core)
MAX + Power (R
OUT)
Total Power + Power (250MHz)
= 155.93mW + 10.7mW + 54.0mW
=220.6mW
