Three 6 -order filters nd provide improved image quality compared to typical 2 rd and 3 -order passive solutions. The FMS6143A 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 (150Ω) or dual (75Ω) video loads. DC coupling the outputs removes the need for large output coupling capacitors. The input DC levels are offset approximately +280mV at the output (see Applications section for details).
