5.5.5.2.1. Differential HSTL, SSTL, HSUL, and POD Termination

Differential HSTL, SSTL, HSUL, and POD inputs use LVDS differential input buffers. However, RD support is only available if the I/O standard is LVDS.

Differential HSTL, SSTL, HSUL, and POD outputs are not true differential outputs. These I/O standards use two single-ended outputs with the second output programmed as inverted.
