Description
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.
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
– DC-coupled inputs
– Each output is capable of driving an AC- or DC-coupled, 150-Ωvideo load at 3 V pp and CVBS output can drive a dual, 75-Ω video load
– Fixed gain of 6 dB for each channel
– Selective video output muting of HD and SD channels
■ 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
– 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
