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).
