Video Filter Driver, Three Channel 4th Order Standard Definition

The FMS6143 Video Filter (LCVF) is intended to replace passive LC filters and drivers with am 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 (see the Applications section for details). The outputs can drive AC-or DC-coupled single (150 Ω) or dual (75 Ω) loads. DC-coupling the outputs removes the need for output coupling capacitors. The input DC levels are offset approximately +280 mV at the output (see Applications section for details).
