Description
The FMS6141 Low-Cost Video Filter is intended to
replace passive LC filters and drivers with a low-cost
integrated device. The 4th-order filter provides improved
image quality compared to typical 2nd or 3rd-order
passive solutions.
The FMS6141 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 an AC-coupled
input is required (see Application Information for details).
The FMS6141’s output can drive an AC- or DC-coupled
single (150 Ω) or dual (75 Ω) load. DC-coupling the
output removes the need for output coupling capacitors.
The input DC level is offset approximately +280mV at
the output (see Application Information for details).

Absolute Maximum Ratings
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables
are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table defines the
conditions for actual device operation.

I/O Configurations
Figure 6 shows a typical AC-coupled input configuration
for driving the filter/driver. Using this configuration, a
0.1µF ceramic capacitor is used to AC couple the input
signal. The coupling capacitor and the input termination
resistor at the input of the filter/driver should be placed
close to the input pin for optimal signal integrity.
