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 selectable between SD and PS filters.
The FMS6246 offers a fixed gain of 6dB. A metal option is available that provides a fixed gain of 9dB, offering even more flexibility.
The FMS6246 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 inputs are required (see applications section for details).
The outputs can drive AC or DC-coupled single (150W) video loads. DC-coupling the outputs removes the need for output coupling capacitors. The input DC levels will be offset approximately +280mV at the output.
