1. Description
The LT9611UX 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. LT9611UX 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 8-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.

1. 描述
LT®9611UXC 是一款面向机顶盒、DVD 应用的高性能 MIPI DSI/CSI 至 HDMI2.0 转换器。
MIPI DSI/CSI 输入具有可配置的单端口或双端口，具有 1 个高速时钟通道和 1~4 个高速数据通道，工作速率最高为 2Gbps/通道，可支持高达 16Gbps 的总带宽。 LT9611UXC 支持突发模式 DSI 视频数据传输，还支持灵活的视频数据映射路径。集成的 DSC 解码器可实现高达 1：3 的视觉无损解压缩，从而降低 UHD 视频传输的带宽要求、功耗和 EMI。
HDMI2.0输出支持高达6Gbps的数据速率，可为4k@60Hz视频提供足够的带宽。此外，HDCP2.2 还支持数据加密。
提供两个数字音频输入接口，I2S 和 SPDIF。I2S 接口支持 2 通道 LPCM，SPDIF 接口支持 2 通道 LPCM 或压缩音频，最大采样率为 192kHz。
该器件能够通过集成微处理器实现自动操作，该微处理器使用嵌入式SPI闪存进行固件存储。系统控制也可通过配置 I2C 从接口实现。
