Color killer threshold
Automatic color killer:
00 = Automatic mode (default)
01 = Reserved
10 = Color killer enabled, the UV terminals are forced to a zero color state.
11 = Color killer disabled
Color killer threshold:
11111 = –30 dB
10000 = –24 dB
00000 = –18 dB (default)

Luminance signal delay with respect to

Luma bypass mode:
0 = Input video bypasses the chroma trap and comb filters. Chroma outputs are forced to zero. (default)
1 = Input video bypasses the whole luma processing. Raw A/D data is output alternatively as UV data and Y
data at SCLK rate. The output data is properly clipped to comply to ITU-R BT.601 coding range. Only
valid for 10-bit YUV output format (YUV output format = 100 or 111 at register 0Dh).
Pedestal not present:
0 = 7.5 IRE pedestal is present on the analog video input signal (default)
1 = Pedestal is not present on the analog video input signal
Luminance bypass enabled during vertical blanking:
0 = Disabled (default)
1 = Enabled
Luminance bypass will occur for the duration of the vertical blanking as defined by registers 18h and 19h. This feature
may be used to prevent distortion of test and data signals present during the vertical blanking interval.
Luma signal delay with respect to chroma signal in pixel clock increments (range –8 to +7 pixel clocks):
1111 = –8 pixel clocks delay
1011 = –4 pixel clocks delay
1000 = –1 pixel clocks delay
0000 = 0 pixel clocks delay (default)
0011 = 3 pixel clocks delay
0111 = 7 pixel clocks delay
