microzed JX1 JX2 pins from differential to single end

Question

Hi Microzed,

I am trying to use Microzed JX1 and JX2 pins (from BANK 34/35/13) as single ended instead of differential.

Read other posts on this forum, such as

http://zedboard.org/content/jx1jx2-track-impedance

http://zedboard.org/content/using-pmod-jc-and-jd-single-ended

But still not clear. Do I need to physically change the resistors on the Microzed board, or how can I control the impedance to make JX1 and JX2 pins as single ended ?

It will be a great help if Microzed expert provides design project in vivado/sdk for me to follow.

Please advise, thanks in advance

Mike

Hello Mike, The 50 Ohm impedance is controlled by the routing done on your carrier board. No Physical resistor needs to be placed for that. --Josh
