ALTGX_RECONFIG MegaWizard Plug-In Manager Setup for Data Rate Division in Transmitter
Mode
Enable the following settings in the ALTGX_RECONFIG MegaWizard Plug-In
Manager for data rate division in transmitter mode:
1. In the Reconfiguration settings screen, set the What is the number of channels
2. Specify the logical channel address of the transmitter channel at the
3. In the Reconfiguration settings screen, select the Data rate division in TX option.
The rate_switch_ctrl[1:0] input port is available when you enable the Data rate
division in TX option. The value you set at the rate_switch_ctrl[1:0] signal
determines the transmitter local divider settings, as explained in
Reconfiguration Controller Port List” on page
To read the existing local divider settings of the transmitter channel, select the Use
'rate_switch_out' port to read out the current data rate division option in the Error
checks/Data rate switch screen.
Decoding for the rate_switch_out[1:0] output signal is the same as the
rate_switch_ctrl[1:0] input signal.
Dynamic rate switch has no effect on the dividers on the receive side of the transceiver
channel. It can be used only for the transmitter.
Data rate division in transmitter mode does not require a .mif.
