Description
The FMS6690 Low Cost Video Filter (LCVF) is intended to
replace passive LC filters and drivers with a low-cost integrated
device. Six 6th 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 simplify DVD video out-
put 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 out-
put or an AC-coupled signal. Internal diode clamps and bias cir-
cuitry may be used if AC-coupled inputs are required (see
applications section for details).
The outputs can drive AC or DC-coupled single (150鈩? video
loads. DC-coupling the outputs removes the need for output
coupling capacitors. The input DC levels will be offset approxi-
mately +280mV at the output.
