Video Filter Driver, Five Channel 4th Order Standard Definition

The FMS6145 Low-Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a low-cost integrated device. Five 4th-order filters provide improved image quality compared to typical 2nd- or 3rd-order passive solutions. The FMS6145 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 the Applications section for details)</i>. 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 are offset approximately +280mV at the output <i>(see the Applications section for details)</i>.
