The Stratix IV GX and GT device provides you the option to select 2.5 V or 3.0 V for
the VCCA_L/R supply through the ALTGX MegaWizard Plug-In Manager. The
Stratix IV GT device only allows 3.3 V for the V
VCCA_L/R value for all the transceiver channel instances to enable the Quartus II
software to place them in the transceiver blocks on the same side of the device. For
example, if you have two ALTGX instances that you would like to place on the left
side transceiver banks GXBL0 and GXBL1, the VCCA_L/R values in the two ALTGX
instances must be the same.
The data rate of the transceiver channel is limited based on the V
selected.
For the data rate restrictions, refer to the
Devices
This section contains information about the gxb_powerdown, reconfig_fromgxb, and
reconfig_togxb ports.
gxb_powerdown Port
The gxb_powerdown port is an optional port that you can enable in the ALTGX
MegaWizard Plug-In Manager. If enabled, you must drive the gxb_powerdown port in
the ALTGX instances from the same logic or the same input pin to enable the
Quartus II software to assign them in the same transceiver block.
reconfig_fromgxb and reconfig_togxb Ports
In the ALTGX MegaWizard Plug-In Manager, the reconfig_fromgxb and
reconfig_togxb ports are enabled if you select one of the following options in the
Reconfig screen:

To combine multiple instances within the same transceiver block:
For example, consider that you want to place a Receiver only and Transmitter only
instance in the same transceiver block. For the Receiver only instance, the Quartus II
software automatically enables the reconfig_fromgxb port. For the Transmitter only
instance, you must select the options in the Reconfig screen (mentioned above) to
enable the reconfig_fromgxb port. In the design, connect these ports from the
Transmitter only and Receiver only instance to the same reconfig controller.
Analog Controls (VOD, Pre-emphasis, Manual Equalization, and EyeQ)
Enable Channel and Transmitter PLL reconfiguration
Offset cancellation for receiver channels (always enabled if the configuration is
Transmitter and Receiver or Receiver only)

The reconfig_fromgxb ports must be enabled in each instance AND
These ports must be connected to the same reconfig controller
