Overview

The FMS6646 Low Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a low-cost integrated device. Six Butterworth filters provide improved image quality compared to typical passive solutions. The combination of low-power Standard-Definition (SD) and High-Definition (HD 1080p) filters greatly simplifies DVD video output circuitry. Three channels offer fixed SD filters, while the other three are selectable between SD and HD filters. The FMS6646 offers a fixed gain of 6dB. The FMS6646 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<I> (see the Applications Information section for details)</I>. The outputs can drive AC- or DC-coupled single (150 Ω ) video loads. DC-coupling the outputs removes the need for output coupling capacitors. The input DC levels are offset approximately +280 mV at the output.
