FMS6246

Six Channel, 6^thOrder SD/PS Video Filter Driver

Features

Description

■ Three selectable sixth-order 8/15MHz (SD/PS) filters

■ Three fixed sixth-order 8MHz (SD) filters

■ Transparent input clamping

The FMS6246 Low Cost Video Filter (LCVF) is intended to

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

device. Six 6th order Butterworth filters provide improved image

quality compared to typical passive solutions. The combination

of low power Standard Definition (SD) and Progressive Scan

(PS) filters greatly simplify DVD video output circuitry. Three

channels offer fixed SD filters while the other three are select-

able between SD and PS filters.

■ Single video load drive (2Vpp, 150Ω, A_V= 6dB)

■ AC or DC-coupled inputs

■ AC or DC-coupled outputs

■ DC-coupled outputs eliminate AC-coupling capacitors

■ Low Power

The FMS6246 offers a fixed gain of 6dB. A metal option is avail-

able that provides a fixed gain of 9dB, offering even more flexi-

bility.

■ 5V only

■ Robust (12kV HBM) output ESD protection

■ Lead (Pb) Free packages- TSSOP-20

The FMS6246 may be directly driven by a DC-coupled DAC out-

put or an AC-coupled signal. Internal diode clamps and bias cir-

cuitry may be used if AC-coupled inputs are required (see

applications section for details).

Applications

■ Cable and Satellite set top boxes

The outputs can drive AC or DC-coupled single (150Ω) video

loads. DC-coupling the outputs removes the need for output

coupling capacitors. The input DC levels will be offset approxi-

mately +280mV at the output.

■ DVD players

■ HDTV

■ Personal Video Recorders (PVR)

■ Video On Demand (VOD)
