ARTIX-7: unused GTP

Jump to solution

Hello,

in our ARTIX-7 design we don't use the GTP-IF.

According the ug482 (page 228) the following pins of the GTP-IF have to be grounded:

1) MGTAVCC

2) MGTAVTT

3) MGTRXP/MGTRXN

4) MGTRREF

 

1) 2) and 4) are clear.

For 3) I'm not sure which of the MGTRXP/MGTRXN I have to ground:

=> all of the MGTPTRXP[0...3] and MGTPTRXN[0...3] ?

 

Thanks

Bodo

Bodo,

Yes, all MGTRXP/MGTRXN 0 through 3.

Hi,

I have similar non-used GTP due to design change, so should I ground ALL pins for GTP including MGTAVTT?

I am doing this spin to reduce power. so my A/D's  go from GTP >> LVDS and I don't want the GTP banks on A200T to be using power if not needed.
