When used as an output, this pin enables power to
downstream USB peripheral 3.
When used as an input, this pin is used to sample
the output signal from an external current monitor
for downstream USB peripheral 3. An overcurrent
condition is indicated when the signal is low.
Refer to
Used for setting HS transmit current level and on-
chip termination impedance. Connect to an
external 12K 1.0% resistor to ground.
Refer to the LAN9512/LAN9512i reference
schematics for additional connection information.
External 25 MHz crystal input.
Note:
External 25 MHz crystal output.
Negative output of the Ethernet transmitter. The
transmit data outputs may be swapped internally
with receive data inputs when Auto-MDIX is
enabled.
Positive output of the Ethernet transmitter. The
transmit data outputs may be swapped internally
with receive data inputs when Auto-MDIX is
enabled.
Negative input of the Ethernet receiver. The receive
data inputs may be swapped internally with
transmit data outputs when Auto-MDIX is enabled.
Positive input of the Ethernet receiver. The receive
data inputs may be swapped internally with
transmit data outputs when Auto-MDIX is enabled.

external 12.4K 1.0% resistor to ground.
Refer to the LAN9512/LAN9512i reference
schematics for additional connection information.
Used for the internal bias circuits. Connect to an
Section 2.1
This pin can also be driven by a single-
ended clock oscillator. When this method
is used, XO should be left unconnected
