Part Number: DS90UB941AS-Q1

Dear Sirs, customer use one lane DSI input and transfer 1.5m distance LVDS display.

engineer plan to use DS90UB941AS-Q1 and DS90UB928 for 1 lane LVDS panel, DS90UB948 for 2 lanes LVDS panel.

the distane is very long, does this solution can support and work for automotive application.

By the way, they demand DS90UB948 output data can divide odd code and even code to each lane output, does DS90UB948 can support this mode or not?

DS90UB948 output panel is Innolux JJ123IA-01J. the panel is 2 LVDS input.

    Hi,

    For UB948's output even/odd output, it can support it per d/s description.

    For your issue, the OpenLDI can't support 1.5m transmission, you need use FPD-Link, the ser. such as UB941as is put close to SoC, and the de-ser such as UB928 is put close to panel. the distance between 941as and 928 can be up to 10m.

    regards,

    Steven
