飛凌科技公司(Infineon Technologies)推出的兩款高度集成的高功效DVB-H/T芯片解決方案：OmniVia TUS9090和OmniTune TUA9000。OmniVia TUS9090是全集成化系統(tǒng)級(jí)芯片(SoC)，包括射頻調(diào)諧器、DVB-H/T解調(diào)器和集成的存儲(chǔ)器。

       OmniTune TUA9000是用于接收DVB-H和DVB-T制式數(shù)字電視信號(hào)的直接轉(zhuǎn)換式多頻段硅調(diào)諧器(VHF、UHF和歐美采用的L頻段)。這些產(chǎn)品面向移動(dòng)數(shù)字電視應(yīng)用，例如手機(jī)、PDA、移動(dòng)媒體播放器和筆記本電腦等。英飛凌推出的這兩款新產(chǎn)品，可使電子系統(tǒng)設(shè)計(jì)實(shí)現(xiàn)化，降低系統(tǒng)成本和功耗，從而終推動(dòng)移動(dòng)電視技術(shù)和產(chǎn)品的發(fā)展和應(yīng)用。
       英飛凌OmniVia TUS9090是用于接收多頻段DVB-H/T信號(hào)的全集成式系統(tǒng)級(jí)芯片(SoC)前端，它集成了射頻硅調(diào)諧器、DVB-H/T解調(diào)器和片上內(nèi)存，可支持多種視頻業(yè)務(wù)的接收。在10%負(fù)載循環(huán)的時(shí)間分片模式下，OmniVia TUS9090可在低于50微毫瓦的功率條件下運(yùn)行，因而具備很高的功率效率.

       O m n i V i a TM is Infineon’s new family of digital broadcast and multimedia products complementing the company’s successful range of radio frequency (RF) Tuner ICs.
       TUS9090, first member of OmniViaTM , is a System on Chip (SoC) front-end receiver for DVB-H/T standard, integrating a RF silicon tuner and a demodulator for multiple services reception without the need of using any external memory. Due to its small footprint area and low power consumption, OmniViaTM TUS9090 is suitable to be built directly into applications like cellular phones, PDA’s and other mobile devices supporting a SDIO/SPI port.
