Description
The FMS6144A Low-Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a th low-cost integrated device.
Four 6 -order filters provide nd rd improved image quality compared to typical 2 and 3 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).
Applications
Cable Set-Top Boxes Satellite Set-Top Boxes DVD Players HDTV Personal Video Recorders (PVR) Video On Demand (VOD)
