USB2.0 Interface
The Kintex Ult FPGA SOM supports one USB2.0 & 3.0 OTG interface on Board-to-Board Connector2 & 1. USB1 controller of
LS1021A is used for USB2.0 & 3.0 OTG interface. The USB OTG controller is capable of fulfilling a wide range of applications for
USB2.0 & 3.0 implementations as a host, a device or On-the-Go. Also, this controller supports all high-speed, full-speed and low-
speed transfers in both device and host modes.
Also, Kintex Ult FPGA SOM supports USB ID & USB VBUS inputs from Board-to-Board Connector2 and connected to USB
PHY for USB Host/Device detection & VBUS monitoring respectively. If USB ID pin is grounded, then USB Host is detected and if it
is floated, USB device is detected.
For more details on USB2.0 OTG Interface pinouts on Board-to-Board Connector2, refer the below table.
