Keywords:Mobile TV SoC? direct-conversion multiband silicon tuner?

Infineon Technologies has added two highly integrated and power-efficient devices to its mobile TV IC family. The OMNIVIA TUS 9090 is a fully integrated SoC that includes a multiband RF tuner, a DVB-H/T demodulator and integrated memory. The OMNITUNE TUA 9001 is a direct-conversion multiband silicon tuner, covering VHF, UHF as well as L-Bands.

With 50 RF inputs and external low noise amplifier (LNA) support, this family is suited for applications that require only a single VHF/UHF antenna input and excellent sensitivity. These products target digital mobile TV applications such as mobile phones, PDAs, mobile media players and laptops.

The OMNIVIA TUS 9090 fully integrated SoC front-end for the multiband worldwide reception of DVB-H/T signals is manufactured using the Infineon 130nm CMOS RF technology. It's available in a SGA, measuring 8.5mm x 8.5mm x 0.8mm, and can also be provided as bare die thanks to flip-chip technology. The die enables handheld device manufacturers to integrate it directly into modules, thus achieving an extremely low profile of less than 1mm.

In time-slicing mode with 10 percent duty cycle, the OMNIVIA TUS 9090 operates at less than 50mW, making this device highly power efficient. The TUS 9090 monolithic IC is fully compliant with MBRAI II specifications. The RF sensitivity is better than -98dBm. The IC hosts the complete firmware, which includes automatic features such as channel profile detection, frequency scanning and PSI/SI parsing. Infineon also provides the drivers, which are compatible with major middleware products.

The OMNITUNE TUA 9001 can fully support multi-band reception for VHF, UHF as well as L-Bands. The device targets digital mobile TV applications such as mobile phones, PDAs, handheld media players and laptops, serving a wide range of regional markets. This compact single-chip also offers unique power optimization by including both a single-supply operation mode that ranges from 2.8V to 3.3V or a dual-supply operation at 1.8/2.8V. In a 10 percent duty cycle mode, the power consumption is only 18mW, up to 25 percent lower than most existing solutions in the market, said Infineon.

Manufactured using the Infineon 130-nm CMOS RF technology, the OMNITUNE TUA 9001 offers a footprint of only 5mm x 5mm and is available as bare die. The device integrates a number of components including the loop filter, crystal oscillator and LNA. In addition, this IC eliminates the need for SAW filters, which further reduces system costs and overall electronics real estate. It saves up to 16mm? of board area compared to existing solutions, said Infineon.

Infineon has showcased and demonstrated its new tuner solutions at this week's Mobile World Congress 2008 in Barcelona, Spain.

The OMNIVIA TUS 9090 and OMNITUNE TUA 9001 are currently sampling with key customers. Mass production for the OMNIVIA TUS 9090 is scheduled for Q3. Mass production for the OMNITUNE TUA 9001 is scheduled for Q2.
