Description
The FMS6246 Low Cost Video Filter (LCVF) is intended to
replace passive LC filters and drivers with a low-cost integrated
device. Six 6th order Butterworth filters provide improved image
quality compared to typical passive solutions. The combination
of low power Standard Definition (SD) and Progressive Scan
(PS) filters greatly simplify DVD video output circuitry. Three
channels offer fixed SD filters while the other three are select-
able between SD and PS filters.
The FMS6246 offers a fixed gain of 6dB. A metal option is avail-
able that provides a fixed gain of 9dB, offering even more flexi-
bility.
The FMS6246 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 (150 Ω ) video
loads. DC-coupling the outputs removes the need for output
coupling capacitors. The input DC levels will be offset approxi-
mately +280mV at the output.
