single link). For YUVA you will need two links (’A’ for YUV and ’B’ for
the key signal). With RGB you will always need two links (’A’ and ’B’,
dual link). The same applies to transmitting rasters of a higher resolu-
tion such as 2K.
However, because Atomix LT provides two independent video channels
(different video rasters and color modes), the secondary B ports can
also be used for the second video channel. Then by default YUV can be
transmitted independently. By changing the speed of the ports to
3-Gbit/s SDI dual-link connections can be realized. They provide all the
features of a standard dual-link connection, but require only one con-
nector instead of two.
The following tables show the signal distribution over the I/O ports for
the different video rasters (color modes) when either one or two video
channels are configured for the board:
