com FMS6141 — Low-Cost, Single-Channel 4th-Order Standard Definition Video Filter Driver November 2006 FMS6141 Low-Cost, Single-Channel 4th-Order Standard Definition Video Filter Driver Features ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ ƒ Single 4th-Order 8MHz (SD) Filter Drives Single, AC- or DC-coupled, Video Loads (2Vpp, 150Ω) Drives Dual, AC- or DC-coupled, Video Loads (2Vpp, 75 Ω) Transparent Input Clamping AC- or DC-Coupled Input AC- or DC-Coupled Output DC-Coupled Output Eliminates AC-Coupling Capacitors Single Supply Robust 10kV ESD Protection Lead-Free Packages: SOIC-8 or SC70-5 Description The FMS6141 Low-Cost Video Filter is intended to replace passive LC filters and drivers with a low-cost integrated device.
The 4th-order filter provides improved image quality compared to typical 2nd or 3rd-order passive solutions.
The FMS6141 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 an AC-coupled input is required (see Application Information for details).
The FMS6141’s output can drive an AC- or DC-coupled single (150 Ω) or dual (75 Ω) load.
DC-coupling the output removes the need for output coupling capacitors.
The input DC level is offset approximately +280mV at the output (see Application Information for details).
