type-c/DP轉(zhuǎn)雙路MIPI信號轉(zhuǎn)換芯片LT7911D方案介紹

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 EmbeddedFlash, LT7911D support EDID buffer, DP/eDP inputdetection 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.
