ALTGX MegaWizard Plug-In Manager Setup for Channel and CMU PLL Reconfiguration Mode
To reconfigure the transceiver channel and CMU PLL, set up the ALTGX MegaWizard
Plug-In Manager as shown in the following steps. The dynamic reconfiguration
controller reconfigures the transceiver channel and the CMU PLL with the new
information stored in the .mif.
1. Select the Channel and Transmitter PLL reconfiguration option in the Reconfig
screen.
2. If you want to reconfigure the data rate of the transceiver channel by reconfiguring
the CMU PLL, provide the new data rate you want the CMU PLL to run at in the
General screen.
3. Provide the logical reference index value in the What is the main PLL logical
reference index? option in the Reconfig Clks screen.
■ Selecting the Logical Reference Index of the CMU PLL
In Figure 2–38, transceiver channel 1 listens to CMU0 PLL of the transceiver block.
