Hi Team,

May you help generate the initial register setting for below structure? Thank you.

Display resolution 756*780@60Hz, 24bpp, MIPI 2 lane input, LVDS 4 lane(single port) output

If you need any other information, feel free to let me know. In addition, does the part only support JEIDA?

Regards,

Roy

Hi Roy,

Here's an guide for generating the configuration for the SN65DSI83/84/85 devices: https://e2e.ti.com/support/interface-group/interface/f/interface-forum/918890/faq-sn65dsi84-how-to-configure-the-sn65dsi84-and-sn65dsi85-for-single-channel-dsi-to-dual-channel-lvds

You can download the DSI Tuner tool (download from the link above) and try it.

Or let me know if I should generate it, but we would need the full display timings including blanking. We would also need the HS/VS/DE polarity, DSI lane count, DSI clock rate, and LVDS clock rate. You can see all the inputs in the step-by-step guide linked above.

Yes, the LVDS output can be either JEIDA or JEIDA format, labelled as Format 1 and Format 2 in the datasheet respectively.

Best regards,
Ikram
