KS8721BL/SL
Micrel
Circuit Design Reference for Power Supply
Micrel’s integrated built-in, voltage regulator technology and thoughtful implementation allows the user to save BOM cost on
both existing and future designs with the use of the new KS8721BL/SL single supply, single port 10/100 Ethernet PHY.

Figure 4. Circuit Design
The circuit design in Figure 4 shows the power connections for the power supply: the 3.3V to VDDI/O is the only input power
source and the 2.5V at VDDRCV, pin 38, is the output of the voltage regulator that needs to supply through the rest of the 2.5V
VDD pins via the 2.5V power plane.
The 2.5V VDD pins make the drop-in replacement with the existing KS8721B/BT part. Table 2 shows the drop-in replacement
from the existing KS8721B/BT to the KS8721SL/BL. Please contact your local Micrel FAE for Application Note AN-117, “Drop-
in Replacement with KS8721BT.”
