Overview
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, lowpass 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 VFQFPN-28 EPD 5× 5 × 1 mm3 (28-pin very fine quad flat pack with exposed pad down) 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 lowpass 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.
