1.  描述
LT7911D是一款高性能DP1.2到MIPIDSI/CSI芯片，適用于VR/智能手機/顯示應用。
對于DP1.2輸入，LT7911D可配置為1、2、4車道，也支持車道交換功能。自適應均衡使其適用于長電纜應用，最大帶寬可達21.6Gbps。
對于MIPIDSI/CSI輸出，LT7911D具有可配置的單端口或雙端口或MIPIDSI/CSI，具有1個高速時鐘通道和1~4個高速數據通道，最大工作在1.5Gb/s/lane，可支持總帶寬高達12Gbps。 LT7911D支持突發模式DSI視頻數據傳輸，也支持靈活的視頻數據映射路徑。
采用先進的MCU和嵌入式Flash, LT7911D支持EDID緩沖，DP/eDP輸入檢測并自動確定進入省電模式。當LT7911D接收機鎖定輸入信號時，單片機可以通過MSA寄存器讀取恢復的定時參數來匹配ASSR。在調試全鏈接訓練時，DPCD寄存器可以通過系統I2C訪問。一旦使用快速鏈接訓練，系統時間將節省至少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.
