The FMS6243 Low-Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a low-cost integrated device. Three fourth-order filters provide improved image quality compared to typical second- or third-order passive solutions.

The FMS6243 can be directly driven by a DC-coupled DAC output or an AC-coupled signal. Internal diode clamps and bias circuitry can be used if AC-coupled inputs are required (see the datasheet Applications section for details).

Delay for each channel can be independently controlled with an external capacitor.

The outputs can drive AC- or DC-coupled single (150W) or dual (75W) loads. DC coupling the outputs removes the need for output coupling capacitors. The input DC levels are offset approximately +280mV at the output (see the datasheet Applications section for details).
