描述 Description

The LT7911UX is a high performance Type-C/eDP/DP1.4 to HDMI2.1 and MIPI®DSI/CSI chip for VR/Smart phone/Display application.

For DP1.4 input, LT7911UX 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 32.4Gbps. The LT7911UX receives both video and audio streams from DisplayPort link and converts to TMDS output. The TMDS transmitter is compliant with HDMI2.1 specification with data rate up to 8Gbps.

For MIPI®DSI/CSI output, LT7911UX features configurable single-port or dual-port or quad-port MIPI®DSI/CSI with 3 high-speed data lanes (1clock lane and 4data lane) operating at maximum 2.5Gsymbol/s/lane, which can support a total bandwidth of up to 68.4Gbps. LT7911UX supports Burst mode DSI video data transferring, also support flexible video data mapping path.

For 2D video stream, the same video stream can be mapped to two separated panel, for 3D video format, left side data can be sent to one panel, and right side data can be sent to another panel.

With sophisticated MCU and the Embedded  Flash, LT7911UX support EDID buffer, DP/eDP input  detection and determine to enter into power saving mode automatically. When the receiver of LT7911UX 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.
