Ps/2 Port; Dual Usb Port - XESS XSV Manual

PS/2 Port

The XSV Board provides a PS/2-style interface (mini-DIN connector J20) to either a
keyboard or a mouse. The FPGA receives two signals from the PS/2 interface: a clock
signal and a serial data stream that is synchronized with the falling edges on the clock
signal.
The following table shows the connections from the FPGA to the PS/2 interface.

Dual USB Port

The XSV Board has a dual-USB interface (J15) that can be connected to a variety of high-
speed or low-speed USB peripherals. The FPGA receives two differential data signals
from each USB port.
