TI's Hollywood Mobile Digital TV Chip Makes Worldwide Premiere
Broadcast digital TV can now be delivered into the cell phones of millions of consumers worldwide while maintaining low cost, long battery life and attractive phone size. Texas Instruments Incorporated announced that initial Hollywood DTV single-chip solutions for mobile phones are now being delivered to TI's customers who manufacture handsets worldwide. TI's Hollywood chips are the first in the industry to integrate the mobile TV tuner and demodulator into one piece of silicon using standard 90 nanometer digital process. Consumers should expect to find the first mobile phones with TI's Hollywood chips inside on the market in late 2006.
TI's first two products in the Hollywood mobile DTV family are the DTV1000 and the DTV1001. As complete solutions, both chips enable mobile TV handsets and services to reach the mass market quickly and at a lower cost to consumers. Hollywood chips support open industry standards, addressing the requirements of customers around the globe. Primary standard support includes DVB-H which is being deployed worldwide including Europe, the U.S. and parts of Asia, and ISDB-T which is being deployed in Japan. DVB-H and ISDB-T use OFDM (orthogonal frequency division multiplexing) technology which provides good spectral efficiency and immunity to multi-path to offer improved mobile TV performance.
In addition, both the DTV1000 and the DTV1001 chips interface with TI's family of OMAP applications processors to deliver crisp, clear video and stereo audio, offering consumers the quality of a living room TV-viewing experience in the palm of their hand.
The DTV1000 supports DVB-H operating at 470-750 MHz (UHF) and 1.670-1.675 GHz (L-band) frequency ranges, while the DTV1001 supports ISDB-T one-segment operating at 470-770 MHz frequency range. Through TI's innovative DRP(TM) technology, the Hollywood devices combine a two-chip or system in package (SIP) solution into a single piece of silicon in standard 90 nanometer digital process to deliver:
- Smallest board area: High degree of integration and low ball count has lead to a footprint of less than 1cm squared for the entire solution including all passive and power switch components which is significantly smaller than current solutions that require a separate tuner, demodulator and external memory.
- Very low power: Low 1 volt RF CMOS process and low power design techniques have resulted in only 30mW of power consumption for a typical category B DVB-H terminal. Combined with TI's low power OMAP application processors this can deliver four to seven hours of view time depending on display size and battery rating.
- Fast Time to Market: Significant value-added processing in the DTV100X results in a simple software driver and API package accelerating integration with host processors, such as OMAP applications processors, and reducing time to market.
- High Performance: Multiple concurrent television channels (elementary streams) can be supported and fast channel switching times under 1.5 seconds are possible.
- Low Part Count and Lower Bill of Materials: High integration has lead to a small number of low cost external components driving the estimated bill of materials in volume under $10.
