Bit Description
Reserved
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 when 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. bad).
CSFM[2:0].
C-Shaping Filter mode allows the
selection from a range of low-pass
chrominance filters, SH1to SH5, and
wideband mode.

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 for the
specified bandwidth.
