Notes to Table 10–5:
(1) These I/O banks support SSTL-18 class II and 1.8- and 1.5-V HSTL class II inputs.
(2) Pseudo-differential I/O standards are only supported for clock inputs and dedicated PLL_OUT outputs. Refer to
Table 10–1 for more information.
(3) This I/O standard is only supported for outputs.
(4) This I/O standard is only supported for the clock inputs.
