Automotive Grade Bridge IC(eDP to Open LDI)

S2D13V70

S2D13V70 is an eDP(rev.1.4a) to Open LDI bridge device which can realize the connectivity between the eDP source to the display panel with the Open LDI interface. It can receive the data rate of 1.62Gbps/2.7Gbps with 1 lane/2lane eDP and convert it to transport with 2ch Open LDI signaling with the pixel clock frequency up to 148.5MHz (per 1ch). The specification is simple enough so that it can be easily inserted into existing system display architectures with minimal modifications required, making it an ideal solution for both existing and future designs.S2D13V70 is also qualified for automotive design including AEC-Q100 certification and several functional safety features.

S2D13V70's eDP Rx IP (rev1.4a) can also connect to DP (rev1.3 and 1.4) signals. Please contact us for details.
