Description

The FMS6346 Low Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a low-cost integrated device. Six 6th order Butterworth filters provide improved image quality compared to typical passive solutions. The combination of low power Standard Definition (SD) and High Definition (HD) filters greatly simplify DVD video output circuitry. Three chan- nels offer fixed SD filters whil e the other three are selectable between SD and HD filters. The FMS6346 offers a fixed gain of 6dB. A metal option is avail- able that provides a fixed gain of 9dB, offering even more flexi- bility. The FMS6346 may be directly driven by a DC-coupled DAC out- put or an AC-coupled signal. Internal diode clamps and bias cir- cuitry may be used if AC-c oupled inputs are required (see applications section for details). 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 will be offset approxi- mately +280mV at the output.
