Description
In Arria® II GX devices, the maximum clock frequency that can be driven by the ALTLVDS_TX megafunction is 800 MHz. To avoid getting the above error in the ALTLVDS_TX MegaWizard™ Plug-In Manager for data rates above 800 Mbps, set the outclock divide factor to a value other than "1" in the Transmitter settings tab.
