Hardware
The DVK board supports USB 3.0 peripheral and Hi-Speed OTG functionality using the J48
connector.
Table 4-2
shows the jumper settings required to operate in USB 2.0 OTG device or Host
mode.
To operate the DVK in USB 3.0 peripheral mode, refer to the default jumper settings mentioned in
Table 3-1 on page 35
and follow the procedure outlined in
USB 3.0 Enumeration on page 54
.

Clocking Mechanism for FX3
FX3 allows either a crystal to be connected between the XTALIN and XTALOUT pins or an external
clock to be connected at the CLKIN pin. The XTALIN, XTALOUT, and CLKIN I/O pins can be left
unconnected if they are not used.

Jumper
Pin Position
Mode: Description
J40
Short
OTG Host: To supply VBUS to the connected peripheral as OTG host
from the power adapter (V5P0).
J50
Short
OTG Host: When connecting a USB device to the FX3 OTG host with a
USB 2.0 Micro-B to Micro-A receptacle cable the OTG_ID pin can be
grounded using this jumper. FX3 then acts as OTG Host by default.
Open
OTG Device: The OTG_ID pin state depends upon the pin state at J48.
The role of FX3 (as the OTG A or B device) depends on the OTG cable
(Micro-A to Micro-B type) orientation.
J47
Short
OTG Host: To select proper capacitance on VBUS between the OTG host
manually short this VBUS_IN jumper.
Open
OTG device: To select proper capacitance on VBUS as the OTG B
device.
J100
1–2
Routes the CTL_4 signal to the Samtec connector (GPIF II interface)
2–3
OTG Host/OTG Device: USB_DRV_VBUS line is connected to the CTL_4
signal. The I/O line can turn the power (VBUS_IN) ON or OFF using
firmware.
