External 5 volt supply enable. This pin is
used to enable the external Vbus power
supply. The CPEN pin is low on POR.
This pad uses VDD3.3 logic level.
ULPI bi-directional data bus. DATA[7] is
the MSB.
ULPI bi-directional data bus.
ULPI bi-directional data bus.
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.
ULPI bi-directional data bus.
ULPI bi-directional data bus. DATA[0] is
the LSB.
1.8V to 3.3V ULPI interface supply
voltage. This voltage sets the value of
V
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.
The Link asserts STP for one clock cycle
to stop the data stream currently on the
bus. If the Link is sending data to the
PHY, STP indicates the last byte of data
was on the bus in the previous cycle.
External 1.8V Supply input pin. This pad
needs to be bypassed with a 0.1uF
capacitor to ground, placed as close as
possible to the USB3317.
