Description
The FMS6690 Low-Cost Video Filter (LCVF) is intended
to replace passive LC filters and drivers with a low-cost
th
integrated device. Six 6 -order Butterworth filters
provide improved image quality compared to typical
passive solutions. The combination of low-power
Standard Definition (SD), Progressive Scan (PS), and
High Definition (HD) filters greatly simplifies DVD video
output circuitry. Three channels offer fixed SD filters
and feature an additional MUXed input, while the other
three channels are selectable between PS and HD
filters. The FMS6690 offers a fixed gain of 6dB.
The FMS6690 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)
video loads. DC-coupling the outputs removes the need
for output coupling capacitors. The input DC levels are
offset approximately +280mV at the output.
Applications
Cable and 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.
