Hello

I'm gonna use "Cyclone V GX starter kit" + "Highspeed AD/DA Card"

http://www.terasic.com.tw/cgi-bin/page/archive.pl?language=english&categoryno=73&no=278

I need to the "Highspeed AD/DA Card" schematic or

How much the input & output impedance of the ADA card?

best regards

Schematic is not present on documentation on board relative CD you can download from terasic site?

Input output impedance is usually set to 50 Ohm as a standard for all high frequency application and or RF if not specified for a different value.
