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.
