Description

The FMS6145 Low-Cost Video Filter (LCVF) is intended

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

integrated device. Five 4th-order filters provide improved

image quality compared to typical 2nd or 3rd-order

passive solutions.

The FMS6145 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 (150Ω) or

dual (75Ω) loads. DC coupling the outputs removes the

need for output coupling capacitors. The input DC levels

are offset approximately +280mV at the output (see

Applications

section for details).
