如何对TYPE-C转HDMI音视频转换电路选择一款有效且合适的方案？针对这一命题，我们分别列出常用的两款方案AG9310和AG9311这两款方案，且这两款方案是Algoltek安格科技 在2019年针对USB TYPE-C扩展坞和USB TYPE-CUSB扩展器市场需求下，新开发的最具性价比的方案芯片。这两款产品分别通用于目前市场上，所有PC端、平板电脑、手机等所有含有USB TYPE-C接口的设备中，其兼容性和匹配度也是最优的。First, we are to be a simple function for the AG9310 and AG9311 Both programs are described:
ALGOLTEK (Engelhard) AG9310 is a realization USB Type-C to HDMI data converters. Support port USB Type-C show an alternative mode, AG9310 video and audio streams may be USB Type-C transmitted from the interface to the HDMI port. In AG9310, the supports 1-way, 2-way different configurations @ 1.62Gbps, 2.7Gbps and 5.4Gbps frequency input, HDMI output support 4K2K @ 30Hz. Manufacturers can use the application AG9310 easy to HDMI Type-C forwarding data converter.
ALGOLTEK (Engelhard) AG9311 is a highly integrated solution, via USB Type-C video and audio output from the DisplayPort alternate mode transmitted to HDMI. AG9311 support various @ 1.62Gbps, 2.7Gbps and 5.4Gbpsup passed to DisplayPort 1.2, one way to support two channels; supports the HDMI 4K / 2K @ 30Hz output. Users can easily be integrated into the AG9311 video conversion adapter and a docking station.
After seeing more than a brief introduction, everyone of these scenarios and features two programs have a rough idea, however, AG9310 and AG9311 in the electrical parameters of the respective characteristics of what is?
We need to understand the detailed parameters to the characteristics of the design parameters of certain high-performance products, more effective product showcase features and selling points, product design process to a concentrated expression of the superiority of the product and market selling point.
