Existing TV decoder chips for set-top boxes in the European market can provide cost-effective support for the recently established Chinese AVS (Audio Video Standard)
Codenamed "Kona", the family builds on the success of ST's widely used "Loihi" and "Lanai" families, and has already been chosen by several LCD monitor makers and by a leading PC manufacturer for their next-generation products. All the members of the family are pin-to-pin and software compatible.
They are the first LCD scalers to be manufactured using an advanced 0.15-micron process technology to give minimum die size, and the first to be available in a small and cost-effective 14 x 14mm 100-pin package.
Commenting on the new family, Philippe Berger, Manager of ST's Display Division, said: "Packing so much dedicated power into such a small package means that the ADE3800 will make a major contribution to cutting costs for LCD-monitor board makers - not just by saving board space, but also through its compatibility with both LVDS and RSDS panels, and the IC's ability to handle analogue, video and dual inputs".
"Coupled with the use of a 0.15-micron production process, the Kona family puts ST at the forefront of chip makers for this market".
The ADE3800 family provides a highly integrated solution for LCD monitor manufacturers, taking an analogue RGB video input signal and generating LVDS or RSDS outputs for LCDs up to SXGA resolution.
As well as high-quality scaling from 5:1 upscale to 2:1 downscale and generating the complex LCD timing signals, the Kona chips include a broad range of additional features designed to improve picture quality and to enhance the end user's experience, while minimising the load on the monitor's microcontroller to allow a simpler and cheaper MCU to be used.

ST is the leading supplier of semiconductors for the CRT display market, and is strongly involved in digital TV, video processing and LCD displays.
Further development of the Kona family will take advantage of this broad experience and of ST's existing IP to provide solutions for emerging LCD applications in multimedia markets, including UXGA displays, multifunction monitors (MFM), low-cost LCD TVs and portable multimedia equipment.
Samples of the first analogue-input device are available now, and volume production is starting in the third quarter of 2004.
Pricing is US $6 in quantities of 1000.
Dual- and triple-input versions will be sampling by the end of the year.
