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
