Table 1–7
Plug-In Manager for your ALTGX custom megafunction variation.
The different dynamic reconfiguration modes available are
listed in the Reconfiguration Settings screen. Based on
which portion of the transceiver you want to reconfigure,
select the corresponding options and connect the
ALTGX_RECONFIG instance to the ALTGX instance.
■
■
These ports provide the interface between the receiver
channel and the dynamic reconfiguration controller.
■
You must enable this option to reconfigure one of the
following: Transmitter local divider block, CMU PLL,
Transceiver channel, or Both the CMU PLL and transceiver
channel.
■
■
lists the different options available in the Modes screen of the MegaWizard
Analog controls (VOD, Pre-emphasis, and Manual
Equalization and EyeQ)—Enable this option to dynamically
reconfigure the PMA control settings similar to VOD,
pre-emphasis, manual equalization, DC gain, and EyeQ.
Enable adaptive equalizer control—Selecting this option
enables the Adaptive Equalization (AEQ) hardware and
provides the following additional ports:
■
■
Offset cancellation for receiver channels—This option is
enabled by default for Receiver only and Receiver and
Transmitter configurations. It is not available for
Transmitter only configurations.
Ensure that you connect a dynamic reconfiguration
controller to all the transceiver channels in the design.
Channel Interface—This option allows channel interface
reconfiguration.
Use alternate CMU Transmitter PLL—This option sets up
the alternate PLL so that the transceiver channel can
optionally select between the output of the main and
alternate transmitter PLL.
Use additional CMU/ATX Transmitter PLLs from outside
the Transceiver Block—This option allows you to select a
maximum of four transmitter PLLs. For example, you can
select the ATX PLL as the main PLL and three additional
PLLs.

How many additional PLLs are used?—You can have a
maximum of two PLLs outside the transceiver block.
