Microtune, Inc. is releasing a dedicated L-Band mobile TV tuners. Complying with the digital video broadcast-handheld (DVB-H) industry standard, the new Mobile MicroTuner MT2262 is a specialized, ultra low-power silicon TV tuner that supports the L-band frequency range (1670-1675 MHz) licensed for mobile broadcast TV services in the USA.
It enables manufacturers to target the US market in bringing high-quality broadcast TV and digital entertainment services to mobile phones, laptops, PDAs and mobile handheld devices.
Built with Microtune's patent-pending Mobile MicroTuner technology, the MT2262 is a sister device to Microtune's MT2260 multi-band DVB-H TV tuner, the first member of the product line which the company unveiled two weeks ago.
Fabricated in silicon germanium, the MT2262 is a single-chip tuner, engineered to deliver a low noise figure for outstanding sensitivity, high linearity for reduced interference and excellent phase noise for maximum video fidelity.
The MT2262 L-band tuner includes all active circuitry required to implement the complete radio frequency (RF)-to-baseband tuner function. A single-ended architecture eliminates the need for a transformer balun, while the L-band low noise amplifier (LNA) has also been fully integrated.
The MT2262 operates from a 2.7V power supply and consumes 20-40 milliWatts in 'viewing' mode, depending on the severity of the reception environment. It features 9-milliWatt power-down and 250-microWatt sleep modes to further conserve battery power. As with the multi-band MT2260 tuner, this low-power consumption enables mobile phone manufacturers to give viewers up to 10 hours of TV viewing time on 2-inch or 4-inch displays using 800mAh or 1300mAh batteries, respectively, for their DVB-H handsets.
The chip measures only 6 x 6-square millimeters and is offered in a 40-pin QFN package. Its miniature size is ideally suited to the significantly reduced footprint designs of leading mobile phone and handheld device manufacturers for their DVB-H handsets.
The MT2262 tuner is sampling starting in July and will be priced at $4.00/unit in quantities of 10,000.
