Description
The FMS6363 Low Cost Video Filter (LCVF) is intended to
replace passive LC filters and drivers with a low-cost integrated
device. Three 6^th order filters provide improved image quality
compared to typical lower order passive solutions.
The FMS6363 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) loads.
DC-coupling the outputs removes the need for output coupling
capacitors. The input DC levels will be offset approximately
+280mV at the output (see applications section for details).
