FMS6246

Six Channel, 6th Order 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 (2V , 150Ω, A = 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

■ DVD players

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.

■ HDTV

■ Personal Video Recorders (PVR)

■ Video On Demand (VOD)
