IS/OD12

(PU)

When used as an output, this pin enables power to

downstream USB peripheral 2.

When used as an input, this pin is used to sample

the output signal from an external current monitor

for downstream USB peripheral 2. An overcurrent

condition is indicated when the signal is low.

Power Supply

VDD18USBPLL

Refer to the LAN9514 reference schematics for

additional connection information.

Crystal Input

ICLK

External 25 MHz crystal input.

Note:

This pin can also be driven by a single-
ended clock oscillator. When this method
is used, XO should be left unconnected
