Small Footprint RMII 10/100 Ethernet Transceiver with HP Auto-MDIX Support
This pin requires connection of a 12.1k ohm (1%)
resistor to ground.
Refer to the LAN8720A/LAN8720Ai reference
schematic for connection information.
Note:
+1.6V to +3.6V variable I/O power
Refer to the LAN8720A/LAN8720Ai 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 LAN8720A/LAN8720Ai reference
schematic for connection information.
Note:
+3.3V Analog Port Power to Channel 1
Refer to the LAN8720A/LAN8720Ai reference
schematic for connection information.
+3.3V Analog Port Power to Channel 2 and the
internal regulator.
Refer to the LAN8720A/LAN8720Ai 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 1.2V and the
resistor will dissipate approximately
1mW of power.
A 1uF decoupling capacitor to ground
should be used on this pin when using
the internal 1.2V regulator.
