- Six Channel, 6th-Order SD/HD 1080p Video Filter Driver July 2009 FMS6646 Six Channel, SD/HD (1080p) Video Filter Driver Features - - - - - - - - - Three Selectable 8/75MHz (SD/HD 1080p) Filters Three Fixed 8MHz (SD) Filters Transparent Input Clamping Single Video Load Drive (2VPP, 150Ω, AV = 6d B) AC- or DC-Coupled Inputs AC- or DC-Coupled Outputs DC-Coupled Outputs Eliminate AC-Coupling Capacitors Low-Power Robust Output ESD Protection: 9k V HBM Description 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 pared to typical passive solutions. The bination 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 6d B. 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 (see the Applications Information section for details). The outputs can drive AC- or DC-coupled single (150Ω) video loads. DC-coupling the outputs removes the need for output coupling capacitors. The input DC levels are offset approximately +280m V at the output. Applications - - - - - Cable and Satellite Set-Top Boxes DVD Players HDTV Personal Video Recorders (PVR) Video On Demand (VOD) ..
