Infineon's Latest Tuner IC Solutions Targeted at Mobile TV Apps

(Product News, 15 Feb 2008)

Infineon Technologies has released two new highly integrated and power-efficient members of its mobile TV IC family—the OMNIVIA TUS 9090, which is a fully integrated System-on-Chip (SoC) that includes a multi-band RF Tuner, a DVB-H/T demodulator and integrated memory, and the OMNITUNE TUA 9001, which is a direct-conversion multi-band silicon tuner, covering VHF, UHF as well as L-Bands. Featuring 50¦¸ RF inputs and external LNA support, the devices are suited for applications that require only a single VHF/UHF antenna input and excellent sensitivity. The chips are targeted at digital mobile TV applications such as mobile phones, PDAs, mobile media players and laptops.

Manufactured using the Infineon 130nm CMOS RF technology, the Infineon OMNIVIA TUS 9090 is available in a semi¨Cball grid array (SGA) of 8.5x8.5x0.8mm package. Alternatively, utilizing flip chip technology, it can also be provided as bare-die. The die enables handheld device manufacturers to integrate it directly into modules, thus achieving an extremely low profile of less than 1mm.

The Infineon OMNITUNE TUA 9001, a direct-conversion RF receiver which can fully support multi-band reception for VHF, UHF as well as L-Bands, 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 1.8V/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.
