Non-Voltage-Referenced Standards
Each I/O bank of a Stratix IV device has its own VCCIO pins and supports only one
V
number of input signals with different I/O standard assignments if it meets the V
and V
For output signals, a single I/O bank supports non-voltage-referenced output signals
that are driving at the same voltage as V
V
For example, an I/O bank with a 2.5-V V
inputs and outputs as well as 3.0-V LVCMOS inputs (but not output or bidirectional
pins).
Voltage-Referenced Standards
To accommodate voltage-referenced I/O standards, each Stratix IV device’s I/O bank
supports multiple VREF pins feeding a common V
VREF pins increases as device density increases. If these pins are not used as VREF pins,
they cannot be used as generic I/O pins and must be tied to V
can only have a single V
time.
An I/O bank featuring single-ended or differential standards can support
voltage-referenced standards if all voltage-referenced standards use the same V
setting.
For performance reasons, voltage-referenced input standards use their own V
level as the power source. This feature allows you to place voltage-referenced input
signals in an I/O bank with a V
HSTL-15 input pins in an I/O bank with 2.5-V V
input with parallel OCT enabled requires the V
voltage of the input standard.
Voltage-referenced bidirectional and output signals must be the same as the I/O
bank’s V
bank with a 2.5-V V
Mixing Voltage-Referenced and Non-Voltage-Referenced Standards
An I/O bank can support both voltage-referenced and non-voltage-referenced pins by
applying each of the rule sets individually. For example, an I/O bank can support
SSTL-18 inputs and 1.8-V inputs and outputs with a 1.8-V V
Similarly, an I/O bank can support 1.5-V standards, 1.8-V inputs (but not outputs),
and HSTL and HSTL-15 I/O standards with a 1.5-V V
