Philips Semiconductors launched a new reference design that enables TV set manufacturers to make a quick and painless migration from CRT to mid-end LCD TV sets.

By rolling out the new reference design - consisting of the company's existing one-chip TV solution called PNX300x and SAA6713 scaler chip - Philips is hoping to capitalize on an explosive demand for flat panel-based TV sets.

Practically all the consumer electronics manufacturers are "moving into LCD TV sets," said Jos Klippert, marketing manager at Philips Semiconductors. They are looking for a solution that lets them "jumpstart quickly in the new market."

According to iSuppli/Stanford Resources, a market research firm, total LCD revenues will reach over $30 billion by the end of 2003 - an increase of 12 percent compared with 2002. Still missing, though, are inexpensive, mid-end LCD TV sets, with all the right TV features, for a volume consumer market.

By using two proven ICs, TV set manufacturers can easily leverage their analog TV software and hardware investment now into the LCD arena, said Klippert. The PNX300x is a system-on-a-chip originally designed to enable digital processing in analog TV, and the SAA6713 is a scaler chip developed for monitor or LCD TV applications.

Further, the system knowledge that comes with the reference design can help the TV set manufacturers "tune the settings for the right picture improvement algorithms optimized for each display - CRT or LCD," added Klippert.

The PNX300x, based on a 54MHz MIPS Technologies processor integrated with advanced geometry correction, is a one-chip TV solution developed for the global market. It integrates multi-standard TV front-end technology for PAL, SECAM, and NTSC video decoding in addition to deinterlacing, advanced scan rate conversion at 100MHz and picture improvement capabilities.

The SAA6713 is a dual-input display controller with integrated ADC for RGB analog sampling up to 110MHz and for DVI implementation.

The reference design is available now. The PNX300x and the SAA6713 scaler together are priced at $20 in volume quantities.
