Luma bypass during vertical
blank
Luminance signal delay with respect
to chrominance signal
Pedestal:
0 =
7.5 IRE pedestal is present on the analog video input (default)
1 =
Pedestal is not present on the analog video input
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 registers 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
