DS90UB948-Q1: Work mode selection

Part Number: DS90UB948-Q1

Hi E2E,

I have a question regarding the mode select table:

If I use the Dual OLDI output, the MAP_SEL can be setted 0 or 1. I noticed that the voltage and R1 R2 are different.

Are there any other differences? How should we determine the value of MAP_SEL?

Thanks

    Hi Tommy,

    The only differences between MODE_SEL0 #0 and #5 is the MAPSEL setting. 

    The value of MAPSEL is determined by referring to the display panel datasheet to see how the incoming RGB data is mapped to the LVDS frame. In the UB948 datasheet, there are figures depicting the differences between MAPSEL = 0 and MAPSEL = H.

    These figures can be found in Section 7.4.3 (OpenLDI Frame and Color Bit Mapping Select).

    Best,

    Jack
