COMB FILTERS
The comb filters of the ADV7183B have been greatly improved
to automatically handle video of all types, standards, and levels
of quality. The NTSC and PAL configuration registers allow the
user to customize comb filter operation, depending on which
video standard is detected (by autodetection) or selected (by
manual programming). In addition to the bits listed in this
section, there are some other ADI internal controls; contact
ADI for more information.
NTSC Comb Filter Settings
Used for NTSC-M/J CVBS inputs.
NSFSEL[1:0] Split Filter Selection NTSC, Address
0x19[3:2]
The NSFSEL[1:0] control selects how much of the overall signal
bandwidth is fed to the combs. A narrow split filter selection
gives better performance on diagonal lines, but leaves more dot
crawl in the final output image; the opposite is true for selecting a
wide bandwidth split filter.
