LVDS Interface
The RS690M contains a dual-channel 24-bit LVDS interface. Notice that for designs implementing only a single LVDS
channel, the LOWER channel of the interface should be used.
2.3.1 LVDS Data Mapping
below shows the transmission ordering of the LVDS signals on the lower and the upper data channels.
The signal mappings for single and dual channel transmission are shown in
respectively.
