DS90UB953A-Q1: FPD-LINK III via SDI

Hello,

I am looking for solution – how to connect remote (30 – 100 meters) CSI-2 camera with CPU CSI-2 input, using one coaxial cable for transfer camera video data in downlink direction; and power and I2C control data from CPU to camera.

FPD-Link III is ideal solution for connect CSI-2 camera and CPU by single cable, but works not longer than 15 meters;

Using FPGA as CSI-2 to serial converter and next SDI for long distance transfer is clear for me, but cost and power expensive.

(I have experience in transfer be-directional data and power using FPGA and Microchip SDI driver-receiver).

Can I use FPD-Link III via SDI cable driver – receiver ?

If FPD-Link III via SDI can’t be used – may be You explain it me in few words, why?

If yes, which SDI cable driver and receiver from TI are best useful as FD-Link III extender?

Best regards, Sergey.

    Hello Sergey,

    can you explain what is SDI and which SDI cable driver are you planing to use?

    Thank You for fast response, Hamzeh.

    In my previous project was used Microchip EQCO30T5-EQCO30R5, for send data from remote FPGA with 1G Ethernet core, and receive power and control via coaxial cable.

    My current task – send CSI-2 data to distance more 30 meters using one coax cable.

    My question is – will FPD-link works another cable driver?

    And, sorry, it was my question ;-)   – which TI products may be used for realization shown in attached picture chain?

    Regards,

    Sergey

    Hello Sergey,

    Depending on your CSI-e payload I suggest you use either the DS90UB935-Q1 or the DS90UB953-Q1 as Serializser.

    As Deserializer I suggest you use the DS90UB936-Q1 or the DS90UB954-Q1.

    I do not see any reason why you should not be able to use our FPD-Link SER-DES in your application.

    I just see one limitation on the Microchip devices that they support a Back Channel of only 5Mbps, where our SER-DES supports up to 50Mbps.
