IP Product: Triple Speed Ethernet with 1588 MegaCore

Why can the LVDS I/O not be selected in the Triple Speed Ethernet MegaCore GUI for Cyclone series devices?


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.
