Description
The FMS6346 Low Cost Video Filter (LCVF) is intended
to replace passive LC fi lters and drivers with a low-cost
integrated device. Six sixth-order Butterworth fi lters pro-
vide improved image quality compared to typical passive
solutions. The combination of low-power Standard-Defi ni-
tion (SD) and High-Defi nition (HD) fi lters greatly simplify
DVD video output circuitry. Three channels offer fi xed SD
fi lters, while the other three are select able between SD
and HD fi lters.
The FMS6346 offers a fi xed gain of 6dB. The FMS6346
may be directly driven by a DC-coupled DAC out put or an
AC-coupled signal. Internal diode clamps and bias
cir cuitry may be used if AC-coupled inputs 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 approxi mately +280mV at the output.
