Description
The STV6430 is a fully integrated solution for filtering and buffering standard-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 STV6430 embeds buffers and low-pass filters (7-MHz, SD filters) and a dual audio amplifier that operates with either differential or single-ended inputs.
FEATUREs
■ I2C bus control
■ Video section:
– 7-MHz, low-pass filters on four encoder
video outputs
– DC-coupled inputs
– 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
– Selectable gain of 6 or 12 dB for each
channel
– 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
