1.5.10. LVDS_FIXED_CLOCK_DATA_PHASE
Specifies exact skew compensation. When the fixed clock-to-data skew is known, clock data synchronization (CDS) can be pre-programmed into the device during configuration. If CDS is pre-programmed into the device, training patterns do not need to be transmitted to the receiver channels. The resolution of each pre-programmed setting is 25% of the data period, to compensate for skew up to 50% of the data period. This option is applied only to input pins that drive the rx_in[] port of the altlvds_rx megafunction. This option is available for APEX II devices only.
