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 (ref. 0 dB = nominal burst amplitude):
11111 = –30 dB
10000 = –24 dB (default)
00000 = –18 dB

Luma bypass during
vertical blank
Luminance signal delay with respect to chrominance signal
Luma bypass mode select:
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 CCIR601 coding range. Only valid for 10-bit YUV output format (YUV output format
= 100 or 111 at register 0D)
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 mode during vertical blanking:
0 = No (default)
1 = Yes
When the luminance bypass is enabled, the luminance comb and notch filters are turned off and the chrominance
components of the output video are sent to a zero color state. Luminance bypass will occur for the duration of the
vertical blanking as defined by register 18 and 19. 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
