Video Filter Driver, Six Channel, 6th Order SD HD

Obsolete

Overview

The FMS6346 Low Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a low-cost integrated device. Six sixth-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 channels offer fixed SD filters, while the other three are select able between SD and HD filters. The FMS6346 offers a fixed gain of 6dB. The FMS6346 may be directly driven by a DC-coupled DAC out put 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 (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.
