STV6440AJT - STMicroelectronics

STV6440AJT Audio/video buffer and 6-channel SD/PS/HD video filter

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 on.

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 si.
