FMS6346

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

Features

Description

■ Three selectable sixth-order 8/32MHz (SD/HD) ﬁlters

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

■ Transparent input clamping

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 pro-

vide improved image quality compared to typical passive

solutions. The combination of low-power Standard-Deﬁni-

tion (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.

■ 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 FMS6346 offers a ﬁxed gain of 6dB. 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).

■ 5V only

■ Robust (12kV HBM) output ESD protection

■ Lead-free package - TSSOP-20

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 are

offset approximately +280mV at the output.

■ DVD players

■ HDTV

■ Personal Video Recorders (PVR)

■ Video On Demand (VOD)
