www.fairchildsemi.com FMS6143 Low Cost Three Channel 4th Order Standard Definition Video Filter Driver Features Description • Three fourth-order 8MHz (SD) filters • Transparent input clamping • Dual video load drive (2Vpp, 75Ω ) • AC or DC-coupled inputs • AC or DC-coupled outputs • DC-coupled outputs eliminate AC-coupling capacitors 5V only • Lead Free package - SOIC-8 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). Applications The outputs can drive AC or DC-coupled single (150Ω) or dual (75Ω) loads. DC-coupling the outputs removes the need for output coupling capacitors. The input DC levels will be offset approximately +280mV at the output (see applications section for details). • Cable set top boxes • Satellite set top boxes • DVD players • HDTV • Personal video recorders (PVR) • Video on demand (VOD) Ordering Information Model Part Number FMS6143 FMS6143 Lead Free Package Container Pack Qty FMS6143CS_NL SOIC-8 Tube 95 FMS6143CSX_NL SOIC-8 Tape and Reel 2500 Temperature range for all parts: 0°C to +70°C.
