Why can the LVDS I/O not be selected in the Triple Speed Ethernet MegaCore GUI for Cyclone series devices? - Why can the LVDS I/O not be selected in the Triple Speed Ethernet MegaCore GUI for Cyclone series devices? Description LVDS I/O cannot be selected in the Triple Speed Ethernet MegaCore ® GUI if the target device is a Cyclone ® series device. This is because the LVDS serializer and deserializers (SerDes) cannot support 1.25 Gbps data rates required by Triple Speed Ethernet.
