Description

The FMS6690 Low-Cost Video Filter (LCVF) is intended

to replace passive LC filters and drivers with a low-cost

integrated device. Six 6

th-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 (150

Ω)

video loads. DC-coupling the outputs removes the need

for output coupling capacitors. The input DC levels are

offset approximately +280mV at the output.
