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.
