FMS6144A
Four-Channel, 6th-Order SD VoltagePlus™ Video Filter Driver
Features
Description
The FMS6144A VoltagePlus™ video filter is intended to
replace passive LC filters and drivers with a cost-
effective integrated device. Four 6th-order filters provide
improved image quality compared to typical 2nd and 3rd
order passive solutions.

Transparent Input Clamping
Supply Range: 3.3V to 5.0V
The FMS6144A 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 the Applications section
for details).
AC- or DC-Coupled Inputs and Outputs
Robust 9kV ESD Protection
Lead-Free TSSOP 14-Pin Package
Applications
The outputs can drive AC- or DC-coupled single (150Ω)
or dual (75Ω) video loads. DC coupling the outputs
removes the need for large output coupling capacitors.
The input DC levels are offset approximately +280mV at
the output (see the Applications section for details).
