Description

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 low-

pass filters, one for HD (selectable 7/15/30 MHz)

and one for SD (7 MHz), and a dual audio

amplifier that operates with either differential or

single-ended inputs.
