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,
Geoff
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?
Hi Alex,
Are you asking for us to help with the design of the Lidar or just help with the DAC?
Regards,
Geoff
Hi Geoff,
We would like to know if the EVM Board can generate a chirp voltage signal with a sample rate of 20 GS/s?
If it is possible, how can it be achieved?
Hey Wen Yen,
The DAC can have up to 6GHz of IBW (baseband) @ 12GSPS. The device does have a dual edge sampling mode which can put spectral content up around 8-10GHz but you would be limited to around 4GHz of IBW in this mode due to the 2x interpolation filter and the close 3rd Nyquist images.
