DDIO Input Speed Cyclone V vs. Cyclone 10GX

When I create a simple DDIO input for both the Cyclone V and Cyclone 10GX parts, the Cyclone V has an Fmax about twice the Cyclone 10GX. Cyclone V, Fmax ~ 400Mhz Cyclone 10GX, Fmax < 200...

    I guess due to my own ignorance. I assumed "EMIF IP" was for external memory interfaces. As I explained, I want to design a deserializer. Is the EMIF IP general-purpose enough for me to use it for a deserializer? I need 8 channels, 64 bits each, 350Mhz DDR clock.
