This pin requires connection of a 12.1 kΩ (1%)
resistor to ground.
Refer to the LAN88710AM/LAN88710BM
reference schematic for connection information.
Note:
+1.6 V to +3.6 V variable I/O power.
Refer to the LAN88710AM/LAN88710BM
reference schematic for connection information.
Supplied by the on-chip regulator unless
configured for regulator off mode via the
REGOFF configuration strap.
Refer to the LAN88710AM/LAN88710BM
reference schematic for connection information.
Note:
+3.3 V Analog Port Power to Channel 1.
Refer to the LAN88710AM/LAN88710BM
reference schematic for connection information.
+3.3 V Analog Port Power to Channel 2 and the
internal regulator.
Refer to the LAN88710AM/LAN88710BM
reference schematic for connection information.
Common ground. This exposed pad must be
connected to the ground plane with a via array.
The nominal voltage is 1.2 V and the
resistor will dissipate approximately
1 mW of power.
A 1 µF decoupling capacitor to ground
should be used on this pin when using
the internal 1.2 V regulator.
