Description
The FMS6144A Low-Cost Video Filter (LCVF) is
intended to replace passive LC filters and drivers with a
low-cost integrated device. Four 6^th-order filters provide
improved image quality compared to typical 2^nd and 3^rd
order passive solutions.
The FMS6144A 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 section for
details).
The outputs can drive AC- or DC-coupled single (150Ω)
or dual (75Ω) video loads. DC coupling the outputs
removes the need for large output coupling capacitors.
The input DC levels are offset approximately +280mV at
the output (see the Applications section for details).
