VIDEO
FILTER/LINE DRIVER
The
FMS6417 is a comprehensive video-filtering and
line-driving solution that offers more functionality than
competitive parts. The FMS6417 is a five-channel video
reconstruction filter that includes selectable RGB (YUV)
high-definition and standard-definition (HD/SD) filters
with Y, C, composite, and modulator outputs. This integrated
product combines video line drivers, sound notch, and
multiple video input/output standards all in one chip.
With
its ability to remove high-frequency noise prior to digitizing
the signal (antialiasing), or to remove artifacts introduced
during D/A conversion in the encoder (reconstruction),
this monolithic device can be used for antialiasing or
reconstructive (smoothing) filtering for RGB, component,
S-video, and composite video signals.
The
FMS6417 consists of a triple sixth order filter with selectable
30- and 8-MHz frequencies and a dual 8-MHz filter for
filtering Y and C. The filter contains a summing circuit
to generate filtered composite video, an audio trap, and
group delay compensation circuits to notch-out audio and
group delay predistortion for NTSC. In addition, 2:1 multiplexers
are provided on the triple filters, as well as provisions
for auxiliary inputs to the composite channel. The FMS6417
also includes DC-coupled inputs, and all outputs can drive
AC-coupled, 75-W loads and provide 6 dB of gain.
This
new video filter is offered in a space- and cost-saving
32-pin LQFP package. It costs $2.70 in 1000-piece
quantities. A demo board is available for $375.
