devices at 311 Mbps. Cyclone II devices cannot receive mini-LVDS data
because the devices are intended for applications where they will be
driving display drivers. A maximum mini-LVDS data rate of 311 Mbps is
supported for Cyclone II devices using DDIO registers. Cyclone II
devices support mini-LVDS only in the commercial temperature range.
