SSTL3_I appears in Figure 47. DC voltage specifications
appear in Table 25 for the SSTL3_I standard. See "DC
Specifications" in Module 3 for the actual FPGA
characteristics.
SSTL3 Class II
A sample circuit illustrating a valid termination technique for
SSTL3_II appears in Figure 48. DC voltage specifications
appear in Table 26 for the SSTL3_II standard. See "DC
Specifications" in Module 3 for the actual FPGA
characteristics.
