Re: Can I use LVDS (in and out) from those banks which is powered from 3.3V?

Hi Gabor,

When you configure a DIO pair as LVDS inputs, the CLIP generator automatically enables the 100 Ohm internal differential input termination on the pair.  You can verify this by inspecting the contraints file (.xdc) generated by the CLIP generator in the same folder as your CLIP .vhd, .xml (for LabVIEW), and .cfg (Config settings for the Generator).  For example, here is the entry in an .xdc file for a differential input I created in the CLIP generator.

#################################################################

# DIO_16

#################################################################

set_property IOSTANDARD LVDS_25 [get_ports {aDio[16]}]

set_property DIFF_TERM TRUE [get_ports {aDio[16]}]

The last page of the CLIP generator will include a path to where these files are placed on disk.
