The FMS6141 Low-Cost Video Filter is intended to replace passive LC filters and drivers with a low-cost integrated device. The 4th-order filter provides improved image quality compared to typical 2nd or 3rd-order passive solutions. The FMS6141 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 an AC-coupled input is required (see Application Information for details). The FMS6141’s output can drive an AC- or DC-coupled single (150 Ohm) or dual (75 Ohm) load. DC-coupling the output removes the need for output coupling capacitors. The input DC level is offset approximately +280mV at the output (see Application Information for details).
