1.  描述
LT7911D是一款高性能DP1.2到MIPIDSI/CSI芯片，适用于VR/智能手机/显示应用。
对于DP1.2输入，LT7911D可配置为1、2、4车道，也支持车道交换功能。自适应均衡使其适用于长电缆应用，最大带宽可达21.6Gbps。
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，最大工作在1.5Gb/s/lane，可支持总带宽高达12Gbps。 LT7911D支持突发模式DSI视频数据传输，也支持灵活的视频数据映射路径。
采用先进的MCU和嵌入式Flash, LT7911D支持EDID缓冲，DP/eDP输入检测并自动确定进入省电模式。当LT7911D接收机锁定输入信号时，单片机可以通过MSA寄存器读取恢复的定时参数来匹配ASSR。在调试全链接训练时，DPCD寄存器可以通过系统I2C访问。一旦使用快速链接训练，系统时间将节省至少400ms。

1. Description

The LT7911D is a high performance DP1.2 to MIPI®DSI/CSI chip for VR/Smart phone/Display application.
For DP1.2 input, LT7911D can be configured as 1,2,4 lane, also support lane swap function. 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 or MIPI®DSI/CSI with 1 high-speed clock lane and 1~4 high-speed data lanes operating at maximum 1.5Gb/s/lane, which can support a total bandwidth of up to 12Gbps. LT7911D supports burst mode DSI video data transferring, also support flexible video data mapping path.
With sophisticated MCU and the Embedded Flash, LT7911D support EDID buffer, DP/eDP input detection and determine 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 full link training. Once the fast link training used, system time will save at least 400ms.
