Figure 4-12 Characteristics of selectable peaking factors
Coring should be switched on by YCOR to reduce noise, which is also amplified when
peaking is enabled. As the coring stage is in front of the peaking filter, 1 LSB noise will
not be peaked.

The chip contains three different matrices, one suited for EBU standards, one suited for
NTSC-Japan and one suited for NTSC-USA, which are selected via MAT. The signal
OUTFOR switches between YUV output or RGB output. The signal UVPOLAR inverts
the U and V channels and results in Y-U-V output. The standard magnitudes and angles
of the color-difference signals in the UV-plane are defined as follows:

The color saturation can be adjusted with SATADJ register in 16 steps between 0 and
1.875. Values above 1.0 may clip the chrominance signals.
