Demo Board Current Consumption
KS8995M/KS8995X
General Description
When the system designer needs to create a power budget
for choosing voltage regulators or for designing power cir-
cuits, numbers for the worst-case current consumption per
voltage rail as measured on the KS8995M/X demo board are
extremely useful.

Max. Current
Voltage Rail Consumption Worst Case
3.3V 110mA All five ports link at 100BT
2.5V 520mA All five ports link at 10BT
1.8V 160mA All five ports link at 100BT
Table 1. KS8995M/X Demo Board Current
Consumption
Operation and Measurement Conditions
The KS8995M/X operates using three dierent voltage rails:
3.3V, 2.5V, and 1.8V.
It can also operate using two separate voltage supplies by
using 2.5V as the digital VDDIO; however, this means that the
MII ports cannot be used.
The measurements shown in Table 1 are for the worst-case
current consumption per voltage rail. They were taken at
room temperature with a trac generator fully loading all ve
ports.
Note that the worst-case current consumption for the 2.5V rail
is in 10BT mode. This is because most of the current draw
from the 2.5V rail is from the Ethernet transceivers. The 10BT
draws more current than 100BT for the transceivers.
Keep in mind that these numbers are for the total power
consumption for these voltages on the entire board, which
includes current drawn by the LEDs and the EEPROM. The
LEDs and EEPROM draw up to 80% of the 3.3V current
shown in Table 1.
Current consumption numbers for the KS8995M/X are given
in the KS8995M/X data sheet.
Please contact your local Micrel FAE or salesperson if you
