Hi,

Referring to the DE2_115_User_manual_2013, page# 41;

additionally, when lvds is used as the i/o standard of the hsmc connector, the lvds receivers need to assemble a 100 ohm resistor between two input signals for each pairs.

I wonder if I have to assemble 100 Ohm resistor myself ? If yes how ? Wouldn't it be difficult to add extra resistor to HSMC ? At least, I didn't find any information if board has 100 Ohm resistor already.

Thanks.
