VGC 596xB chipMicronas unveiled a highly integrated IC family that promises to take HDTV picture quality on LCD and Plasma TVs to new levels of performance.

Designed for advanced flat panel display TVs, the VGC 596xB family of dual-channel video and graphics controllers supports full HDTV resolution. Two fully independent channels allow the screen to display two images side-by-side, as Double Window, PIP, or as Picture-and-Text (PAT), while preserving full image resolution and optimizing picture quality.

"There are two complete signal paths and both have been designed for optimum image quality," explained Peter Kliegelhoefer, Product Marketing Manager for Micronas' consumer products. "We are convinced that customers will appreciate the uncompromised clarity of pictures for both high-definition and standard-resolution sources."

Micronas added that the best-in-class picture quality is achieved with a combination of advanced picture improvements, including dynamic contrast enhancement, luminance and chrominance sharpness enhancement, selective color enhancement, non-linear color-space enhancement, and content-adaptive temporal noise reduction. All of these are available for both channels independently and support either LCD or Plasma Display Panels (PDP).

With a 32bit MIPS processor, the VGC 596xB allows maximum flexibility. In addition to controlling the TV set, software-driven features can be added. Hardware and software are also performance-optimized around a fast RTOS.

"The high-level drivers facilitate the software development, but we make sure designers have full control of all picture parameters," added Kliegelhoefer. "Major TV manufacturers are moving towards Linux-like software architectures and we have adopted this approach to reduce development time and effort."

Composite video, quad CVBS

The VGC 596xB supports all relevant input formats, including 1,080p and various PC resolutions. The company explained that the triple 10bit video ADCs preserve image quality from computers or other analog sources, making PC-TV integration easy. Composite video, quad CVBS, triple Y/C and triple component inputs are also supported. The built-in switch matrix allows any input to be selected for either channel.

Micronas added that its unique video signal path architecture is 10 bits or better throughout the device, and all elements are sized for full HDTV (1,080p) image processing. Two separate color decoders with 2D/3D comb filters for NTSC and PAL eliminate irritating chrominance and luminance artifacts.

The VGC 596xB family is offered in two versions: the VGC 5969B for HDTV 1,080p panels, and the VGC 5968B for WXGA panels. Both versions are pin and software compatible, enabling scalable TV applications with only one PCB design. Additionally, the new chip meets all requirements for the European HD-Ready label. For the U.S. and Korean markets, Micronas offers an ATSC-compliant HDTV solution proposal based on its DRX 3942H ATSC front-end device family in combination with an MPEG decoder.

The VGC 596xB is already sampling, with production scheduled in Q1 2006. In addition, evaluation boards, development tools and a comprehensive TV software package including a flat panel display TV application example will be available. Additional information on the VGC 596xB can be found at the company's website.
