Power
N/A ID pin of the USB cable. For non-OTG
applications this pin can be floated. For
an A-Device ID is grounded. For a B-
Device ID is floated.
N/A VBUS pin of the USB cable. This pin is
used for the Vbus comparator inputs and
for Vbus pulsing during session request
protocol.
N/A Regulator input. The regulator supply can
be from 5.5V to 3.1V.

N/A 3.3V Regulator Output. A 2.2uF (<1 ohm
ESR) bypass capacitor to ground is
required for regulator stability. The
bypass capacitor should be placed as
close as possible to the USB3319.
N/A D- pin of the USB cable.

N/A 60MHz reference clock output. All ULPI
signals are driven synchronous to the
rising edge of this clock.
The system must not drive voltage on the
CLKOUT pin following POR or hardware
reset that exceeds the value of VIH_ED.
N/A ULPI bi-directional data bus.
