1 Introduction to USB Download Cable
The USB Download Cable interfaces a USB port on a host computer to an FPGA
mounted on a printed circuit board. The cable sends configuration data from the host
computer to a standard 10-pin header connected to the FPGA. You can use the USB
Download Cable to iteratively download configuration data to a system during
prototyping or to program data into the system during production.

2 Specifications for USB Download Cable
A 10-pin surface mount header can be used for the JTAG, AS, or PS download cable.
However, Intel recommends using a through-hole connector because of the repeated
insertion and removal force needed.
