Description
The FMS6143A Low-Cost Video Filter (LCVF) is
intended to replace passive LC filters and drivers with a
th
low-cost integrated device. Three 6 -order filters
nd
provide improved image quality compared to typical 2 -
rd
and 3 -order passive solutions.
The FMS6143A 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).
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 Applications section for details).
Applications
Cable Set-Top Boxes
Satellite Set-Top Boxes
DVD Players
HDTV
Personal Video Recorders (PVR)
Video On Demand (VOD)

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.
