Description
The FMS6646 Low Cost Video Filter (LCVF) is intended
to replace passive LC lters and drivers with a low-cost
integrated device. Six Butterworth lters provide
improved image quality compared to typical passive
solutions. The combination of low-power Standard-
Denition (SD) and High-Denition (HD 1080p) lters
greatly simplifies DVD video output circuitry. Three
channels offer xed SD lters, while the other three are
selectable between SD and HD lters.
The FMS6646 offers a xed gain of 6dB.
The FMS6646 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 Information
section for details)
.
The outputs can drive AC- or DC-coupled single (150)
video loads. DC-coupling the outputs removes the need
for output coupling capacitors. The input DC levels are
offset approximately +280mV at the output.
