Description
The FMS6141 Low -Cost Video Filter is intended to replace
passive LC filters and drivers w ith 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 +280 mV at the
output (see Application Information for details).
