Hi all,

Anyone have an idea about LVDS convert to CSI-2  help me pls?. I don't have an idea about it yet.

Thank you all,

  • Hello Bang, 
     
      For FPD LVDS to RGB data, use an FPD LVDS receiver like the DS90CF386. Other FPD LVDS Receivers here http://www.ti.com/lsds/ti/interface/flatlink-fpd-link-lvds-for-lcd-products.page might work too depending upon the bit resolution and data rate needed. Follow the DS90CF386 with DS90UR905Q-Q1 => DS90UR910-Q1 (see the DS90UR910-Q1 data sheet, pg. 1).

     

    Total possible solution: DS90CF386 => DS90UR905Q-Q1 => DS90UR910-Q1


     
    Regards

    Hi Joel,

    I need convert CSI-2 out with 4 lane data + 1 lane clock, but i read DS90UR910-Q1 output have only 2 lane data + 1 lane clock. So can you help me IC convert out CSI-2 with 4 lane data + 1 lane clock?.
    Thanks!

    Best regards,

    Hello Bang,

    I'm sorry to say that we do not have a 4 lane + clk CSI-2 output device in our portfolio.

    Hello Jeffery Pfarr,

    My solution convert LVDS to CSI-2 is: LVDS => DS90UH947-Q1 => DS90UH940-Q1 => CSI-2. 

    I use single LVDS ( 4 data lane + 1 clock) to DS90UH947-Q1, so DS90UH947 can support 1920x1080p with 60 frame per second?. And How many bit DS90UH947 can transfer maximum?. Can up to 2Gbps?.

    I 'm looking forward to hearing from you soon.

    Best regards,

    Hi Bang,

    It looks like the 940 deserializer does have selectable 2 or 4 lane CSI-2 output with one clock lane and up to 2 FPD-Link III inputs. The 947 serializer accepts LVDS input (18 or 24 bit RGB) and has up to 2 FPD-Link III outputs. Both devices support HDCP if you need that (depending upon device version), WUXGA (1920 x 1200 resolution), Max pixel clock rate of 170 MHz and Max Throughput Rate of 5.95 Gbps. I've asked the engineering team that supports these devices to comment on support for 1920x1080p at 60 Hz Frame rate and any other application details they wish to highlight. From my point of view it looks like your solution may work!

    Hi Jeffery,

    Thank you so much. Can you help me setting DS90UH947-Q1 use only 4 lane data LVDS + 1 lane clock?.

    And if i use 4 lane LVDS + 1 clock input, output 1 or 2 lane FPD Link III?.

    Have a nice day.

    Best regards,

    Why can't you just use:

    DS90UR907Q-Q1 => DS90UR910Q-Q1

    The DS90UR907 web link is:

    Hi Jeong,

    I understand your 's resolution. But I need convert LVDS to 4 lane data + 1 lane clock CSI-2 so I can't use DS90UR907Q-Q1 => DS90UR910-Q1.

    So you can help me about DS90UH947 and DS90UH940?.

    Best regards,

    Bang

  • In reply to Bang Duong:

    Hi Bang,

    The DS90UH947 auto detects the DS90UH940, I would need a more specific question than "So you can help me about DS90UH947 and DS90UH940?"

    By the way are you an HDCP adopter?

    If not you can use the DS90UB947 and the DS90UB940.
