Message Text: Texas Instruments today introduced a new analog-to-digital (A/D) video decoder that combines four independent video decoders into a single chip.

The new TVP5154 quad A/D video decoder simplifies layout and saves up to 25 percent in board space over previous products. In addition, each channel of the TVP5154 features a programmable horizontal/vertical (H/V) scaler that can offload processing from associated video processors, giving developers additional headroom for value-added algorithms.

The growth of the security and surveillance market has fueled demand for the inexpensive format conversion of video captured by traditional analog cameras. The TVP5154 quad-channel video decoder is designed to meet this demand. Accepting two composite inputs per decoder for a total of up to eight separate camera inputs, the TVP5154 converts NTSC, PAL and SECAM formats to digital video output streams. Patented technology helps improve the quality of weak, noisy or unstable signals, and additional support is provided for non-standard video signals.

The TVP5154 quad video decoder is in production today and is available through TI and authorized distributors. The device is packaged in a space- saving 16mm x 16mm, 128-pin low-profile quad flatpack (LQFP). Pricing is $9.00 per unit in quantities of 1,000 units.

The TVP5154 evaluation module (EVM) with the DM642 video processor provides a evaluation platform with integrated DSP code, Windows control software, and an encoder daughter card for video output. The control software provides one-click settings for a variety of standard downscaled resolutions, including VGA, QVGA, CIF, QCIF and SIF, among others. The EVM is scheduled for release by the end of April 2006, with pricing planned at $649 per unit.
