Infineon drives digital mobile TV with tuner IC solutions

(Product News, 15 Feb 2007)

Infineon Technologies, provider of communication ICs, announced two new integrated, DVB-H/T chip solutions: the OmniVia TUS9090, an integrated system-on-chip (SoC) that includes the RF Tuner, DVB-H/T demodulator and integrated memory, and the OmniTune TUA9000, a direct-conversion multi-band Silicon Tuner (VHF, UHF as well as the L-Bands for Europe and North America) for the reception of both DVB-H and the DVB-T Digital TV transmission signals. These products are targeted at mobile digital TV applications such as mobile phones, PDAs, mobile media players and laptops.

The Infineon OmniVia TUS9090 is an integrated SoC front-end for the multi-band worldwide reception of DVB-H/T signals, integrating the RF Silicon Tuner, DVB-H/T demodulator as well as on-chip memory with support for multiple service reception. In time-slicing mode with 10 percent duty cycle, the OmniVia TUS9090 operates at less than 50mW, making this device highly power efficient.

Manufactured using the Infineon 130nm CMOS RF technology, the Infineon OmniVia TUS9090 is available packaged at a dimension of only 8x8x0.8mm. Optionally, it can also be provided as bare die (bumped flip chip) which enables handheld device manufacturers to integrate it directly into modules and thus achieve an extremely low profile of less than 1mm.

The Infineon OmniTune TUA9000 is a direct-conversion RF receiver that supports multi-band reception for both the DVB-H and the DVB-T standards. OmniTune TUA9000 targets digital Mobile TV applications, such as mobile phones, PDAs, handheld media players, and laptops, serving the wide range of regional markets adopting the DVB-H/T standards. The compact single-chip also offers power optimization with both single-supply operation at 2.8V and dual-supply operation at 1.8V/2.8V. In 10% duty cycle mode, the power consumption is only 18mW.

Manufactured using the Infineon 130nm CMOS RF technology, the OmniTune TUA9000 has a footprint of only 5x5mm and can optionally be offered as bare die. OmniTune TUA9000 integrates a number of components, including the loop filter, crystal oscillator and LNA (low noise amplifier) and, in addition, eliminates the need for SAW (Surface Acoustic Wave) filters, which further reduces system costs and overall electronics real estate. Thus, the Infineon OmniTune TUA9000 saves up to 16 mm of board area compared to existing solutions.

Prof. Dr. Hermann Eul, executive vice president and member of the Infineon management board and president of communication solutions business group, said: "The OmniVia TUS9090 and the OmniTune TUA9000 primarily address mobile applications. These new solutions offer system IP blocks to further complement our mobile handset platform for high-end phones. With mobility being an ever-increasing trend, mobile TV capabilities will become a key market differentiator for handsets. Today, we are well-positioned in this market segment due to our advanced process technology, IP, baseband and RF system know-how. Our latest digital tuner and demodulator ICs enable our customers to enter and competitively participate in this emerging market through our value-add advanced solutions."
