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.

ULPI bi-directional data bus. DATA[7] is
the MSB.

ULPI bi-directional data bus.
60MHz reference clock output. All ULPI
signals are driven synchronous to the
rising edge of this clock.

ULPI bi-directional data bus.
ULPI bi-directional data bus. DATA[0] is
the LSB.
The PHY asserts NXT to throttle the data.
When the Link is sending data to the
PHY, NXT indicates when the current
byte has been accepted by the PHY. The
Link places the next byte on the data bus
in the following clock cycle.
Controls the direction of the data bus.
When the PHY has data to transfer to the
Link, it drives DIR high to take ownership
of the bus. When the PHY has no data to
transfer it drives DIR low and monitors
the bus for commands from the Link.
