DAC39RF12: Which EVM board that can be used to generate arbtrary waveform? Sample rate of >20 GSa/s

Wen Yen Chang

Part Number: DAC39RF12
Other Parts Discussed in Thread: DAC39RF10EVM, , TRF1108

Tool/software:

HI!  I am Alex work in Delta Electronics, Inc. in Taiwan.

We would like to purchase an EVM board that can be used to generate arbtrary waveform.

Is there any EVM board that can be programmed to generate arbitrary waveforms? My requirement is a sample rate of >20 GSa/s.

What is the difference between the DAC39RF10EVM and the TRF1108-DAC39RFEVM?

Can they be used as an AWG?

If so, could you arrange for someone to provide a demonstration and training on how to use them?

    Hi Wen,

    We do not currently have a DAC that is 20GS/s, the DAC39RF12 is 12GS/s. 

    The difference between the two boards is that the TRF1108 one has an amplifier on the output.

    Regards,

    Geoff

    Hi Geoff,

     

    From the data sheet (attached picture), the spec i see is 2400 Msps. The device can generate signal up to 12GHz signal bandwidth.


    Do I have any misunderstandings about this specification? 

     

    Even if this model has a sample rate of only 12 GSa/s, can it still be used to programmatically generate arbitrary waveforms?

    Can DAC39RF10EVM or TRF1108-DAC39RFEVM be use to generate arbitrary waveforms?

    Hi Wen,

    Yes, the DAC can be used to create an ARB patterns up to 12GHz.

    I’m Alex from Delta Electronics in Taiwan.

    We’re interested in purchasing an EVM board, and I’d like to use the EVM board to generate ARB patterns.

    Could you arrange a demo for us?

    I’ve tried reaching out to your local sales representatives in Taiwan, but I haven’t received any responses to my emails.

    When I call, the sales representatives answer and say they will follow up, but I never hear back afterward.

    Hi Alex,

    can you give me more information about your end application. What are you using the DAC for?

    Regards,

    Hi Geoff,

    I want to use the EVM board to output a sinusoidal voltage signal with a frequency that varies over time.

    This signal will be fed into an IQ modulator so that the laser can be modulated to generate a chirped signal, which can be used for FMCW ranging in LiDAR applications.

    The frequency variation range is from 1 GHz to 9 GHz.

    Do you have any idea to do this?
