Interfacing ALTGX and ALTGX_RECONFIG Instances
f
Use the ALTGX_RECONFIG MegaWizard Plug-In Manager to instantiate the
dynamic reconfiguration controller.
For more information, refer to the
Guide.
The reconfig_clk Clock Requirements for the ALTGX_RECONFIG Instance
You must connect the reconfig_clk input port of the ALTGX_RECONFIG instance to
the same clock that is connected to the reconfig_clk input port of the ALTGX
instance.
Table 5–3 on page 5–4
reconfig_clk input port for the Receiver only, Receiver and Transmitter, and
Transmitter only configuration modes of the ALTGX instance.
Based on the ALTGX configurations (Receiver only, Transmitter only, and Receiver
and Transmitter) controlled by the ALTGX_RECONFIG instance, select the fastest
reconfig_clk frequency value. This satisfies both the offset cancellation control for
the receiver channels and the dynamic reconfiguration of the transmitter and receiver
channels.
To dynamically reconfigure the transceiver channel, you must understand the
concepts related to interfacing the transceivers with the dynamic reconfiguration
controller. These concepts are:

Logical Channel Addressing
The dynamic reconfiguration controller identifies a transceiver channel by using the
logical channel address. The What is the starting channel number? option in the
ALTGX MegaWizard Plug-In Manager allows you to set the logical channel address of
all the channels within the ALTGX instance.
For channel reconfiguration with transmitter PLL select mode, the logical channel
addressing concept extends to transmitter PLLs. For more information, refer to
“Logical Channel Addressing When Using Additional PLLs” on page
The following sections describe the concept of logical channel addressing for ALTGX
instances configured with:
