FMS6346E VoltagePlus video filter is intended to replace passive LC and drivers with a costeffective integrated device. Six Butterworth improve image quality compared to typical passive solutions. The combination of low-power SD and HD greatly simplifies DVD video output circuitry. Three channels offer SD 6th-order while the other three are selectable between SD and HD 7th-order

The FMS6346E offers a gain of 6dB.

The FMS6346E 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 the Applications Information section for details .

The outputs can drive AC- or DC-coupled single video loads. DC-coupling the outputs remove the need for output coupling capacitors. The input DC levels are offset approximately +280mV at the output.
