Other Parts Discussed in Thread: DRA829

Hi Team,

The specification of output chip is

and the display input is

I need SerDes transmission, Mipi to BT.1120 or BT.1120 to BT.1120
Is there any device recommended?

Beat Regards,
Tom Liu

    Hello Liu,

    We do not have any discrete devices which convert MIPI CSI-2 to BT.1120. It may be possible using a video processor solution so I will move your question to a different part of the forum

    Best Regards,

    Casey

    Hi Casey ,

    Thank you for your reply.
    I post again to Processor forum. Is it correct?

    Tom, 

    The image of video output is not readable on the post above. can you resend the part number?

    If I understand the system requirements - it requires 4x parallel input ports, and three overlay managers, then drive out three port displays: one MIPI DSI, two parallel ports. Please confirm this is the correct understanding. 

    The only processor chip we have that support mipi-DSI is DRA829x. It does support two additional parallel ports, and have 4 overlay manager. So you will need to need another device that bridges the two graphics channel from parallel ports to something DRA829 can take, either via CSI-2 input, or via PCIe. But please note that this solution will not be cost-optimized, as there are many subsystems on DRA829 that will not be used. 

    let me know if you want to proceed further. Then we will need to check latency requirement. 

    regards
