3.1.1 Video Channel Mapping
The 30 bit video input signals are mapped to the RGB and YCbCr color space according to the options described
in the following table:
Table 2: Video Channel Mapping
Option D[29:20] D[19:10] D[9:0]
#1 RED (Cr) GREEN (Y) BLUE (Cb)
#2 RED (Cr) BLUE (Cb) GREEN (Y)
#3 GREEN (Y) RED (Cr) BLUE (Cb)
#4 GREEN (Y) BLUE (Cb) RED (Cr)
#5 BLUE (Cb) RED (Cr) GREEN (Y)
#6 BLUE (Cb) GREEN (Y) RED (Cr)
The AMN11310 allows any of the input video channels options. The first option is the default from power-up. In
