FMS6346 -- Six Channel, 6th-Order SD/HD Video FIlter Driver

May 2007

FMS6346 Six Channel, 6th-Order SD/HD Video Filter Driver
Features
Three selectable sixth-order 8/15MHz (SD/HD) filters Three fixed sixth-order 8MHz (SD) filters Transparent input clamping Single video load drive (2Vpp, 150, AV 6dB) AC- or DC-coupled inputs AC- or DC-coupled outputs DC-coupled outputs eliminate AC-coupling capacitors Low power 5V only Robust (12kV HBM) output ESD protection Lead-free package - TSSOP-20

Description
The FMS6346 Low Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a low-cost integrated device. Six sixth-order Butterworth filters provide improved image quality compared to typical passive solutions. The combination of low-power Standard-Definition (SD) and High-Definition (HD) filters greatly simplify DVD video output circuitry. Three channels offer fixed SD filters, while the other three are selectable between SD and HD filters. The FMS6346 offers a fixed gain of 6dB. A metal option is available that provides a fixed gain of 9dB, offering even more flexibility. The FMS6346 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) video loads. DC-coupling the outputs removes the need for output coupling capacitors. The input DC levels are offset approximately 280mV at the outpu
t.

Applications
Cable and satellite set-top boxes DVD players HDTV Personal Video Recorders (PVR) Video On Demand (VOD)
