Analog Devices Unveils Multi-Standard Terrestrial Mobile TV RF TunersWednesday, September 9th, 2009
ADI’s tiny-footprint, VHF/UHF digital TV RF tuners are compatible with global terrestrial mobile TV standards for China, Japan, Korea, Europe and the U.S.
NORWOOD, MA — Analog Devices, Inc. (NYSE:ADI), a global leader in high-performance semiconductors for signal-processing applications, extended its mobile television RF (radio frequency) product family with the introduction today of the industry’s smallest terrestrial mobile TV RF tuners. Compatible with global terrestrial mobile TV standards, ADI’s ADMTV803 and ADMTV804 RF tuners consume 60 percent less power and are 50 percent smaller than competing tuners, helping to prolong battery life and improve the user experience for mobile phone, notebook PC, and PDA (personal digital assistant) applications.
The multi-standard tuners support China’s CMMB (UHF band), TMMB and DTMB standards, as well as global terrestrial TV standards, including DVB-H, DVB-T (Europe), DAB (Europe), T-DMB (Korea), ISDB-T: full-seg, 3-seg and 1-seg (Japan) and ATSC-M/H (USA). Mobile TV is a service that allows viewers to watch television on their cell phones, notebook PCs or PDAs; and terrestrial TV refers to modes of television broadcasting, such as over cellular networks, that do not involve transmissions via satellite or underground cables.
ADI’s new radio chips allow mobile handset and portable and consumer electronic device manufacturers to develop and ship mobile TV products capable of supporting multiple standards, providing greater market leverage from a single design. This lowers BOM (bill of materials) costs and reduces board footprint for manufacturers while meeting the needs of network operators and content providers for faster time-to-market for new mobile TV services.
“Analog Devices has shipped approximately 20 million RF tuners worldwide and has had market share leadership in China since 2007, when ADI sold the world’s first CMMB tuner into the Chinese mobile TV market; today, most CMMB terminals have ADI RF tuners inside,” said Brian Kim, general manager, Integrant Technologies Division, Analog Devices. “The success ADI has experienced, not only in China but in Korea and Japan as well, has served as the springboard for an expanded class of RF tuners to satisfy emerging U.S. and European mobile TV standards. ADI has developed chips that allow consumers in any part of the world – using any mobile TV broadcasting standard — to enjoy the highest quality reception while on the move.”
According to ABI Research, the size of the global mobile TV market for products, content and services could top $50 billion USD by 2013. The ADMTV803 and ADMTV804 are the latest in a series of mobile TV products ADI has developed to meet this market demand.
RF Tuners: Small Size, Low Power, Worldwide Compatibility on a Single Chip
The single-chip tuners feature low power consumption of 90 mW and are each housed in a 4 mm x 4 mm LFCSP package. The ADMTV803 low power tuner supports the UHF (470 MHz to 860 MHz) broadcast frequencies of China’s CMMB mobile TV standard, cutting the component count of other solutions by up to 50 percent.
The ADMTV803 provides excellent signal reception with a low noise figure of 2.5 dB. Its high linearity allows a sufficient margin for an adjacent channel-interference rejection ratio when supporting DVB-T/ISDB-T standards. Additionally, the ADMTV803 integrates external passive devices required to configure the RF tuner circuitry making it is easier to configure space-constrained mobile TV systems.
The ADMTV804 features all the functionality of the ADMTV803 with the addition of an LDO (low drop-out regulator). The LDO reduces BOM cost and was designed for the China (CMMB standard) and the U.S. (ATSC-M/H standard) market.
