Video filter
Fairchild Semiconductor
The FMS6146 Low-Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a low-cost integrated device. Six 4th-order filters provide improved image quality compared to typical 2nd or 3rd-order passive solutions.
The FMS6146 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 (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 Applications section for details).
