The LVDS_25 standard is available in the HD I/O banks. See the
UltraScale
Architecture SelectIO Resources User Guide (UG571) for more information.

- LVDS_25 in HD I/O banks supports inputs
only. LVDS_25 inputs without internal termination have no VCCO requirements. Any VCCO can be chosen as
long as the input voltage levels do not violate the Recommended
Operating Condition (Table 1)
specification for the VIN I/O pin voltage.
- Maximum VIDIFF value is specified for the maximum VICM
specification. With a lower VICM, a higher VDIFF is tolerated only when the recommended operating
conditions and overshoot/undershoot VIN specifications
are maintained.
