1. 描述 LT9611UXC是一个高性能的MIPI DSI/CSI到HDMI2.0转换器，用于机顶盒，DVD应用程序。 MIPI DSI/CSI输入具有可配置的单端口或双端口，1个高速时钟通道，1~4个高速数据通道，最大工作速率为2Gbps/lane，总带宽可达16Gbps。 LT9611UXC支持突发模式DSI视频数据传输，并支持灵活的视频数据映射路径。 集成的DSC解码器实现了高达1:3的视觉无损解压缩，降低了超高清视频传输的带宽需求，也降低了功耗和EMI。 HDMI2.0输出支持高达6Gbps的数据速率，这为4k@60Hz视频提供了足够的带宽。 数据加密也支持HDCP2.2。 提供两个数字音频输入接口，I2S和SPDIF。 I2S接口支持2-ch LPCM, SPDIF接口支持2-ch LPCM或压缩音频，最大采样率为192kHz。 该设备能够自动操作，这是由一个集成的微处理器，使用嵌入式SPI闪存固件存储。 系统控制也可通过配置I2C从接口。 2. 特性 •单/双端口MIPI DSI/CSI接收器 •数字音频输入 •HDMI2.0发射机 •杂项 3. 应用程序 •机顶盒 •DVD / BD •PTV盒子 1. Description The LT9611UXC is a high performance MIPI DSI/CSI to HDMI2.0 converter for STB, DVD applications. The MIPI DSI/CSI input features configurable single-port or dual-port with 1 high-speed clock lane, and 1~4 high-speed data lanes operating at maximum 2Gbps/lane, which can support a total bandwidth of up to 16Gbps. LT9611UXC supports burst mode DSI video data transferring, also supports flexible video data mapping path. Integrated DSC decoder implements up to 1:3 visually lossless decompression which reduces bandwidth requirement for UHD video transport, also power consumption and EMI. The HDMI2.0 output supports data rate up to 6Gbps which provides sufficient bandwidth for 4k@60Hz video. Also HDCP2.2 is supported for data encryption. Two digital audio input interfaces are available, I2S and SPDIF. The I2S interface supports 2-ch LPCM and the SPDIF interface supports 2-ch LPCM or compressed audio, both at maximum 192kHz sample rate. The device is capable of automatic operation which is enabled by an integrated microprocessor that uses an embedded SPI flash for firmware storage. System control is also available through the configuration I2C slave interface. 2. Features • Single/Dual-Port MIPI DSI/CSI Receiver • Digital Audio Input • HDMI2.0 Transmitter • Miscellaneous 3. Applications • STB • DVD/BD • PTV Box
