Bit Description
Reserved
CCLEN; current clamp
enable allows the user
to switch off the current
sources in the analog
front
Reserved
Reserved
DCFE; digital clamp
freeze enable
DCT[1:0]; digital clamp
timing determines the
time constant of the
digital fine clamp circuitry
Reserved
YSFM[4:0]; selects Y
shaping filter mode in
CVBS-only mode;
allows the user to select
a wide range of low-pass
and notch filters; if either
auto mode is selected,
the decoder selects
the optimum Y filter
depending on the CVBS
video source quality
(good vs. poor)
CSFM[2:0]; C shaping filter
mode allows selection
from a range of low-pass
chrominance filters;
if either auto mode is
selected, the decoder
selects the optimum C
filter depending on the
CVBS video source quality
(good vs. bad); nonauto
settings force a C filter for
all standards and quality
of CVBS video

Notes
Decoder selects
optimum Y
shaping filter
depending on
CVBS quality
If one of these
modes is selected,
the decoder does
not change filter
modes; depending
on video quality, a
fixed filter response
(the one selected)
is used for good
and bad quality
video
Automatically
selects a C filter
based on video
standard and
quality
Selects a C filter for
all video standards
and for good and
bad video
