STV6440
Audio/video buffer and 6-channel SD/PS/HD video filter
Data brief
Features
■ I²C bus control
■ Video section:
– Selectable 7-MHz/15-MHz/30-MHz, low-
pass filters, plus bypass, on three encoder
video inputs
– 7-MHz, low-pass filters on three encoder
video inputs
– DC-coupled inputs
– Each output is capable of driving an AC- or
DC-coupled, 150-Ω video load at 3 V pp
and provides a 6-dB gain. One output can
drive a dual, 75-Ω video load
– Selective video output muting
■ Audio section:
– Stereo sound capability
– Differential or single-ended audio inputs
– Audio outputs drive 2-kΩ loads at 3 V RMS
– Selectable audio gain of 0 to 28 dB
– Audio output muting
– 9 V to 12 V single supply operation
– Click-noise suppression management
– Pop-noise suppression management
■ Low power mode
– Audio/video standby function

Applications
■ Set-top boxes (IP, cable, satellite, terrestrial)
■ Integrated digital TV plug-in
■ Blu-ray and DVD players
Description
The STV6440 is a fully integrated solution for
filtering and buffering standard-definition,
progressive-scan and high-definition signals, and
buffering stereo audio signals from the MPEG
decoder of a digital receiver, Blu-ray or DVD
player, or iDTV plug-in.
The STV6440 embeds two triple buffers with low-
pass filters, one for HD (selectable 7/15/30 MHz)
and one for SD (7 MHz), and a dual audio
amplifier that operates with either differential or
single-ended inputs.
