FMS6143 Low-Cost Three-Channel 4th-Order Standard Definition Video Filter Driver
Features
Three 4th-order 8MHz (SD) filters Drives single, AC- or DC-coupled, video loads (2Vpp, 150) Drives dual, AC- or DC-coupled, video loads (2Vpp, 75) Transparent input clamping AC- or DC-coupled inputs AC- or DC-coupled outputs DC-coupled outputs eliminate AC-coupling capacitors 5V only Robust 8kV ESD protection Lead-free SOIC-8 package

Description
The FMS6143 Low-Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a low-cost integrated device. Three 4th-order filters provide improved image quality compared to typical 2nd or 3rd-order passive solutions. The FMS6143 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 Applications section for details). The outputs can drive AC- or DC-coupled single (150) or dual (75) loads. DC-coupling the outputs removes the need for output coupling capacitors. The input DC-levels are offset approximately 280mV at the output (see the Applications section for details).

Applications
Cable set-top boxes Satellite set-top boxes DVD players HDTV Personal Video Recorders (PVR) Video On Demand (VOD)
