Three Channel 4th Order Standard Definition Video Filter DriverGeneral DescriptionThe FMS6143 Low-Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a low-cost integrated device. Three 4th-order filters provide improved image quality compared to typical 2nd- or 3rd-order passive solutions. The FMS6143 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 I(see the Applications section for details)/I. The outputs can drive AC-or DC-coupled single (1500Ω) or dual (750Ω) loads. DC-coupling the outputs removes the need for output coupling capacitors. The input DC levels are offset approximately +280mV at the output (see IApplications/I section for details). Product Status/Pricing/Packing
