SOG Threshold [4:0]: Sets the voltage level of the SOG slicer comparator. The minimum setting is 0 mV and the maximum is 350 mV. The
step is 11.2 mV. (default 17h, 10h recommended)
Blue Clamp Select: When free running mode this bit is no effect
0 = Bottom level clamp (default)
1 = Mid level clamp
Green Clamp Select: When free running mode this bit is no effect
0 = Bottom level clamp (default)
1 = Mid level clamp
Red Clamp Select: When free running mode this bit is no effect.
0 = Bottom level clamp (default)
1 = Mid level clamp
NOTE:
Bottom level clamping is required for Y and RGB inputs, while mid level clamping is
required for Pb and Pr inputs. The internal clamp pulse must also be correctly
positioned for proper clamp operation. See register 05h.

Sync Separator Threshold [7:0]
Sync Separator Threshold [7:0]: Sets how many internal 5 MHz clock periods the sync separator will count to before toggling high or low.
SyncSeparator Threshold [7:0] x 133 ns must be greater than the width of the negative sync pulse. This setting can also affect the position of
VSOUT. See register 22h.
