1． 描述 LT6911UXB是一款高性能HDMI2.0到MIPI DSI/CSI转换器，适用于VR，智能手机，显示应用。 HDMI2.0输入支持高达6Gbps的数据速率，这为4k@60Hz视频提供了足够的带宽。HDCP2.2也支持数据解密。 对于MIPI DSI/CSI输出，LT6911UXB具有可配置的单端口、双端口或四端口MIPI DSI/CSI，具有1个高速时钟通道和1~4个高速数据通道，最大工作在2Gbps/lane，可支持总带宽高达32Gbps。LT6911UXB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编码器实现了高达3:1的视觉无损压缩，降低了超高清视频传输的带宽需求，功耗和EMI。 提供两个数字音频输出接口，I2S和SPDIF。I2S接口支持8通道LPCM, SPDIF接口支持2通道LPCM或压缩音频，两种接口的采样率均为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 •HDMI2.0接收机 •单/双/四端口MIPI DSI/CSI发射器 •数字音频输出 •杂项 3.应用程序 •移动系统 •显示 •虚拟现实 1. Description The LT6911UXB is a high performance HDMI2.0 to MIPI DSI/CSI converter for VR, Smart phone, Display applications.
The HDMI2.0 input supports data rate up to 6Gbps which provides sufficient bandwidth for 4k@60Hz video. Also HDCP2.2 is supported for data decryption.
For MIPI DSI/CSI output, LT6911UXB features configurable single-port, dual-port or quad-port MIPI DSI/CSI 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 32Gbps. LT6911UXB supports burst mode DSI video data transferring, also supports flexible video data mapping path. Integrated DSC encoder implements up to 3:1 visually lossless compression which reduces bandwidth requirement for UHD video transport, also power consumption and EMI.
Two digital audio output 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.
