NOTES
1
Allows the user to influence the time constant of the system depending on the input video quality.
2
Allows the user to enable/disable the square pixel operation.
3
Allows the user to select a differential input mode for every entry in the INSEL[3:0] table.
4
4 F
SC
Mode. Allows the selection of a special NTSC mode where the data is resampled to 4 F
SC
sampling rate. As a result the LLC will operate at a 4 F
SC
rate as well.
Only valid for NTSC input.
5
NTSC only
6
Automatic Startup Enable. When set a change in the INSEL register will automatically be detected and lead the device to enter a video reacquire mode. May be
disabled for genlocked video sources.
