1. 描述
LT7911D是一款用于VR /智能電話/顯示應用的高性能DP1.2至MIPI?DSI/ CSI芯片。
對于DP1.2輸入，LT7911D可以配置為1,2,4通道，還支持通道交換功能。自適應均衡使其適合長電纜應用，最大帶寬高達21.6Gbps。
對于MIPI?DSI/ CSI輸出，LT7911D具有可配置的單端口或雙端口或MIPI?DSI/ CSI，具有1個高速時鐘通道和1?4個高速數據通道，其最大速度為1.5Gb / s / lane，它可以支持高達12Gbps的總帶寬。LT7911D支持突發模式DSI視頻數據傳輸，還支持靈活的視頻數據映射路徑。
憑借先進的MCU和嵌入式閃存，LT7911D支持EDID緩沖器，DP / eDP輸入檢測并確定自動進入省電模式。當LT7911D的接收器鎖定輸入信號時，MCU可以通過MSA寄存器讀取恢復的時序參數以匹配ASSR。調試完整的鏈接訓練時，可通過系統I2C訪問DPCD寄存器。一旦使用了快速鏈接訓練，系統時間將至少節省400ms。

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.
