Conexant Systems Inc. has introduced an A/V decoder for PC TV applications and CE products.

The CX25845 is an A/V decoder that aims to improve picture quality for broadcast video programming on digital TVs, STBs, digital video disc recorders and Windows Media Center Edition PCs.

The A/V decoder integrates three functionsa multiformat video decoder, a 3D comb filter and a worldwide broadcast audio decoder. The device is based on NTSC and PAL industry standards.

A 3D comb filter separates the black and white from the color picture content that resides in a composite video signal. It uses multiple frames of video stored on the integrated memory to determine the areas of image processed as black and white versus color to provide a sharper image.

The CX25845 is sampling today with volume production scheduled for January 2007. The chip is packaged in a Pb-free, 80-pin exposed thin quad flat pack (ETQFP), and is priced at $8 per unit in production quantities.
