Electrical Specifications

5.8

Power Dissipation

The Intel^®IXP45X and Intel^®IXP46X Product Line of Network Processors were tested assuming

a typical worst case networking application under a tester environment. The following power

assessments in Table 83 assume this typical worst case networking application using the interface

activity factors listed in Table 84. The actual power may vary if interface activity factors are

different from Table 84. If applications do not require use of certain peripherals or if interfaces

operate at lower activity factors, then the power required by the part may be significantly less than

the numbers stated in Table 83.

† Power in mW is calculated using Maximum Vcc specification for each power rail.

Activity factor is directly proportional to the overall power consumption where each application

will have a different activity factor and different power conclusion. Table 84 illustrates the activity

factor of each interface on the tester during the typical worst case networking application.

1. All output clocks toggling at their specified rate.

2. Tester did not include termination resistors on any interface for power analysis.

3. Tester measures power at 85 degrees F Ambient.

4. Current measurements are average and not peak.

5. Intel XScale^®Core processor tested running DSP software.
