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. It embeds buffers and low-pass filters (7-MHz, SD filters) and a dual audio amplifier that operates with either differential or single-ended inputs. It features I2C bus control, selectable gain for the video section, selective video output muting, selectable gain for the audio section, and audio output muting.
The STV6430 is a fully integrated solution designed to filter and buffer standard-definition video signals and stereo audio signals. It embeds buffers with 7-MHz low-pass filters and a dual audio amplifier capable of operating with differential or single-ended inputs.
This device manages slow and fast blanking signaling via the I2C bus and supports applications in set-top boxes, integrated digital TV plug-ins, Blu-ray players, and DVD players. It offers features such as selectable video gain (6 or 12 dB), audio output muting, click-noise suppression, and low-power standby modes.
