英飛凌OmniVia TUS9090 DVB-H/T解決方案

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是全集成化系統級芯片(SoC)，包括射頻調諧器、DVB-H/T解調器和集成的存儲器。

OmniTune TUA9000是用于接收DVB-H和DVB-T制式數字電視信號的直接轉換式多頻段硅調諧器(VHF、UHF和歐美采用的L頻段)。這些產品面向移動數字電視應用，例如手機、PDA、移動媒體播放器和筆記本電腦等。英飛凌推出的這兩款新產品，可使電子系統設計實現最小化，降低系統成本和功耗，從而最終推動移動電視技術和產品的發展和應用。

英飛凌OmniVia TUS9090是用于接收多頻段DVB-H/T信號的全集成式系統級芯片(SoC)前端，它集成了射頻硅調諧器、DVB-H/T解調器和片上內存，可支持多種視頻業務的接收。在10%負載循環的時間分片模式下，OmniVia TUS9090可在低于50微毫瓦的功率條件下運行，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.
