英飞凌科技公司(Infineon Technologies)推出的两款高度集成的高功效DVB-H/T芯片解决方案：OmniVia TUS9090和OmniTune TUA9000。OmniVia TUS9090是全集成化系统级芯片(SoC)，包括射频调谐器、DVB-H/T解调器和集成的存储器。OmniTune TUA9000是用于接收DVB-H和DVB-T制式数字电视信号的直接转换式多频段硅调谐器(VHF、UHF和欧美采用的L频段)。这些产品面向移动数字电视应用，例如手机、PDA、移动媒体播放器和笔记本电脑等。英飞凌推出的这两款新产品，可使电子系统设计实现最小化，降低系统成本和功耗，从而最终推动移动电视技术和产品的发展和应用。
英飞凌OmniVia TUS9090是用于接收多频段DVB-H/T信号的全集成式系统级芯片(SoC)前端，它集成了射频硅调谐器、DVB-H/T解调器和片上内存，可支持多种视频业务的接收。在10%负载循环的时间分片模式下，OmniVia TUS9090可在低于50微毫瓦的功率条件下运行，因而具备很高的功率效率.
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.
