An I/O bank featuring single-ended or differential standards can support
voltage-referenced standards as long as all voltage-referenced standards
use the same V
implement both SSTL-3 and SSTL-2 I/O standards, I/O pins using these
standards must be in different banks since they require different V
values
For voltage-referenced inputs, the receiver compares the input voltage to
the voltage reference and does not take into account the V
Therefore, the V
Voltage-referenced bidirectional and output signals must be the same as
the I/O bank’s V

Mixing Voltage Referenced & Non-Voltage Referenced
Standards
Non-voltage referenced and voltage referenced pins can safely be mixed
in a bank by applying each of the rule-sets individually. For example, on

outputs with a 1.8-V V
