Description
The FMS6346 Low Cost Video Filter (LCVF) is intended
to replace passive LC lters and drivers with a low-cost
integrated device. Six sixth-order Butterworth lters pro-
vide improved image quality compared to typical passive
solutions. The combination of low-power Standard-Deni-
tion (SD) and High-Denition (HD) lters greatly simplify
DVD video output circuitry. Three channels offer xed SD
lters, while the other three are selectable between SD
and HD lters.
The FMS6346 offers a xed gain of 6dB. A metal option is
available that provides a xed gain of 9dB, offering even
more exibility.
The FMS6346 may be directly driven by a DC-coupled
DAC output or an AC-coupled signal. Internal diode
clamps and bias circuitry may be used if AC-coupled in-
puts are required (see Applications section for details).
The outputs can drive AC- or DC-coupled single (150Ω)
video loads. DC-coupling the outputs removes the need
for output coupling capacitors. The input DC levels are
offset approximately +280mV at the output.
