FMS6143
Low Cost Three Channel 4th Order Standard
Definition Video Filter Driver
Features
• Three fourth-order 8MHz (SD) filters
• Transparent input clamping
• Dual video load drive (2Vpp, 75Ω )
• AC or DC-coupled inputs
• AC or DC-coupled outputs
• DC-coupled outputs eliminate AC-coupling
capacitors 5V only
• Lead Free package - SOIC-8
Description
The FMS6143 Low Cost Video Filter (LCVF) is intended to
replace passive LC filters and drivers with a low-cost
integrated device. Three 4th order filters provide improved
image quality compared to typical 2nd or 3rd order passive
solutions.
The FMS6143 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 (150
Ω
) or
dual (75
Ω
) loads. DC-coupling the outputs removes the need
for output coupling capacitors. The input DC levels will be
offset approximately +280mV at the output (see applications
section for details).
Applications
• Cable set top boxes
• Satellite set top boxes
• DVD players
• HDTV
• Personal video recorders (PVR)
• Video on demand (VOD)
