LT7911D 是一款高性能 DP1.2 至 MIPIDSI/CSI 芯片，适用于 VR/智能手机/显示应用。 对于 MIPIDSI/CSI 输出，LT7911D 具有可配置的单端口或双端口或 MIPIDSI/CSI，具有 1个高速时钟通道和 1~4 个高速数据通道，最高工作速率为 1.5Gb/s/通道，可支持高达 12Gbps 的总带宽。LT7911D 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。 对于LVDS输出，LT7911D可配置为单端口或双端口。对于2D视频流，相同的视频流可以。映射到两个分离的面板，对于3D视频格式，可以将左侧数据发送到一个面板，右侧数据发送到另一个面板。 
LT7911D内置MCU和flash，支持EDID缓冲器。DP/eDP输入检测，自动确定进入省电模式。当LT7911D接收机锁定输入信号，单片机通过MSA寄存器读取恢复的定时参数。来匹配ASSR。当调试连接训练时，DPCD寄存器可以通过系统12C访问。 特性 Type-c DP/eDP Receiver 单/双端口MIP DSICSI发射机 单/双端口LVDS发射机 1.1. Description The LT7911D is a high performance Type-C to MIPI®DSI/CSI chip for VR/Display application. For DP1.2 input, LT7911D can be configured as 1/2/4 lane. Adaptive equalization makes it suitable for long cable application and the maximum bandwidth is up to 21.6Gbps. For MIPI®DSI/CSI output, LT7911D features configurable single-port or dual-port MIPI®DSI/CSI with 1 high-speed clock lane and 1~4 high-speed data lanes operating at maximum 1.5Gbps/lane, which can support a total bandwidth of up to 12Gbps. LT7911D supports burst mode DSI video data transferring, also supports flexible video data mapping path. For LVDS output, LT7911D can be configured as single-port or dual-port. For 2D video stream, the same video stream can be mapped to two separated panels, for 3D video format, left side data can be sent to one panel, and right side data can be sent to another panel. With embedded MCU and flash, LT7911D supports EDID buffer, DP/eDP input detection and determines to enter into power saving mode automatically. When the receiver of LT7911D locks the input signal, MCU can read the recovered timing parameters by MSA registers to match the ASSR. The DPCD registers are accessible via system I2C when debugging the link training. 2.
