LVDS Bridge requirement for CM4 IO board.pdfOur MPU is CM4. We have designed a customized CM4 carrier board as per our requirements in Rev1.0 design. Now we want to include LVDS display connector in our design. As said in the document CM4 has 2 channel and 4 channel DSI provision, taking these as inputs we have to give provision for LVDS Display. Please suggest a bridge IC for this requirement. Please let me know for any clarifications.

Thanks & Regards,

Hey Sai,

For this application it seems you are going from single link of DSI to a single link of LVDS. The best pat for this application in the SN65DSI83/ SN65DSI83-Q1. The Q1 is the automotive qualified version of the part. This will be able to handle 2 channel and 4 channel DSI.

Hi Vishesh,

Thanks for your reply, hope you have gone through the requirements file which i have shared and you understood. You have seen the 2 channel DSI pins and 4 channel DSI pins on CM4 and we need converter to drive these to LVDS display. If we have to use SN65DSI83-Q1 part. please suggest what could be the signals traced on to the 30pins connector (LVDS connector).

Best Regards,

Sai Ravali

The DSI83 has a 4 lane data and 1 lane clock DSI input; it also has a 4 data lane and 1 clock lane LVDS output. You will only need 1 DSI83.
