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

Favorite

Overview

The FMS6690 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), Progressive Scan (PS), and High Definition (HD) filters greatly simplify DVD video output circuitry. Three channels offer fixed SD filters and feature an additional MUXed input, while the other three channels are selectable between PS and HD filters. The FMS6690 offers a fixed gain of 6dB. The FMS6690 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 applications 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 will be offset approximately +280 mV at the output.
