STV6437

Audio/video buffer and four-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 filter on one encoder

video input

VFQFPN-28 EPD 5× 5 × 1 mm³

– DC-coupled inputs

(28-pin very fine quad flat pack with exposed pad

– Each output is capable of driving an AC- or

DC-coupled, 150-Ω video load at 3 V pp

and CVBS output can drive a dual, 75-Ω

video load

Applications

■ Set-top boxes (IP, cable, satellite, terrestrial)

■ Integrated digital TV plug-in

■ Blu-ray and DVD players

– Fixed gain of 6 dB for each channel

– Selective video output muting of HD and

SD channels

■ Audio section:

Description

– 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

The STV6437 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.

– 9 V to 12 V single supply operation

– Pop-noise suppression management

The STV6437 embeds four buffers with low-pass

filters, three 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.

■ Low power mode

– Audio/video standby function
