DM3725 CSI2/DSI support

Other Parts Discussed in Thread: DM3730

Hello!


I'm sorry to raise this question yet again, but I really need some clarifications directly applicable to my case.

I'm designing a board which I plan to hook up to two cameras and an OLED display via two CSI2 and DSI respectively. MY first problem is worded almost verbatim in this thread:

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/537/t/261091.aspx

Now I see that there are probably no problems with CSI2. But the question with the DSI is still open.

The second problem is with the datasheet, namely the signal description and ball characteristics tables. I can't find the CSI2/DSI signals in the datasheet so I can't be sure where to route these differential pairs. Can you help me?

Thank you in advance!

    Hi,
    You can find description of the Display pad group configurable interface in the DM3730/25 TRM Table 13-26. Signal Group Parameter Controls to Different Interface I/O Pads Mapping at page 2481.
    Also look at the DSI serial interface schematics in section 7.2.1.2 DSI Serial Interface - Figure 7-33.
