DDC2256A: Digital readout-circuit design for the DDC2256A

Part Number: DDC2256A

Hello,

I want to develop a compact digital readout circuit for two DDC2256A devices.

I've already inspected the DDC2256EVM and designed an analog circuit with our sensors and two DDC2256A devices which can be read out using the digital board of the EVM and the TI DDC2256_EVM_GUI software.

In the next step I want to develop my own digital readout-circuit for my analog board.

Since I'm a physicist and yet have never touched FPGA-programming, my first question is, whether it is possible to controll the two DDC2256A devices using a microcontroller and if so, can you recommend a suitable device?

In case it is not possible to use a microcontroller, can you provide a minimum FPGA-based design approach?

My ultimate goal would a compact USB-powered handheld device for our sensors based on two DDC2256As.

Many thanks in advance for your advice!

Best regards

Alexander

  • Hi Alexander,

    I have not kept up with microcontrollers, but while the programming control signals could likely be generated by an MCU, the output data comes out on a fast serial stream (>100 Mbps) which I am not sure MCUs can handle. Usually folks use FPGAs for this but if you can find an MCU, it'll probably make your whole project much easier, I agree...

    In that sense, about the FPGA code, let me check but I don't think it would include the whole thing you are describing...

    Regards,

  • Hi again,

    Looks like we do share the FPGA code if needed so just let us know if you want to go down that path... You can reach through the same channels you got the DS or just reply here and we will contact you.

    Best regards,

    Eduardo

  • Hi Eduardo,

    Thank you very much for your reply. Yes, I would take you up on your offer and have a look at the FPGA code. Please contact me.
    Thanks in advance!

    Best regards,

    Alexander
