Dedicated L-band mobile TV tuner targets U.S. DVB-H apps
June 22, 2005 Plano, TX -- From Microtune, the MT2262 is a specialized, low-power silicon TV tuner that complies with the digital video broadcast-handheld (DVB-H) industry standard, with dedicated support for the L-band frequency range (1670-1675 MHz) licensed for mobile broadcast TV services in the U.S. The company says the tuner enables manufacturers to bring high-quality broadcast TV and digital entertainment services to cell phones, laptops, PDAs, and other mobile devices.
June 22, 2005 Plano, TX -- From Microtune, the MT2262 is a specialized, low-power silicon TV tuner that complies with the digital video broadcast-handheld (DVB-H) industry standard, with dedicated support for the L-band frequency range (1670-1675 MHz) licensed for mobile broadcast TV services in the U.S. The company says the tuner enables manufacturers to bring high-quality broadcast TV and digital entertainment services to cell phones, laptops, PDAs, and other mobile devices.
Based on the company's patent-pending Mobile MicroTuner technology, the MT2262 is a sister device to the company's recently introduced MT2260 multi-band DVB-H TV tuner. According to the company, fabricated in silicon germanium, the single-chip MT2262 is engineered to deliver a low noise figure for outstanding sensitivity, high linearity for reduced interference, and excellent phase noise for maximum video fidelity.
The company says the MT2262 L-band tuner includes all active circuitry required to implement complete radio frequency (RF)-to-baseband tuner functionality. The chip's single-ended architecture eliminates the need for a transformer balun; the chip also features a fully integrated L-band low noise amplifier (LNA). The company says this design approach reduces components, cost, and power for manufacturers seeking to incorporate mobile TV capability into high-volume handsets.
The tuner operates from a 2.7-V power supply and consumes 20-40 mW in "viewing" mode, depending on the severity of the reception environment. The device's 9-mW power-down and 250-µW sleep modes further conserve battery power. The company says the tuner's low-power consumption enables mobile phone manufacturers to provide viewers with up to 10 hours of TV viewing time on 2-inch or 4-inch displays, using 800-mAh or 1300-mAh batteries, respectively, for DVB-H handsets.
The MT2262 measures 6 x 6-mm², comes in a 40-pin QFN package, is pin-compatible with the multi-band MT2260 device, and is designed to interface directly with most DVB-H demodulators. The tuner is sampling starting in July, and will be priced at $4.00/unit in quantities of 10,000.
