Dear Sir,

We use TSW1400EVM for our data capture and playback purpose. but I have some question below,

We found that what we need not only the TSW1400EVM but also a ADC/DAC module board to implement the DAQ function. Am I right?

If I am right , could you help check for me that the DAC/ADC module – AFE7222EVM can integrate on the TSW1400EVM kit to implement the DAQ function?

If not, please give us some recommend for the DAQ function integrated with TSW1400E

Thnaks.

Hi,

Yes, you need an ADC/DAC EVM to go with the TSW1400EVM. Also the AFE7222EVM is supported on the TSW1400.

Thanks,

Eben.

Hi Paaserby,

This error usually means that the TSW1400EVM is not getting a clock from the AFE7225EVM. Can you confirm that you are providing a clock to the AFE7225EVM? What is the sampling frequency so that I can bring this up in the lab to verify.

Thanks,

Eben.

Dear Eben,

thanks for your help , currenlty , AFE722x board can be used, but here still have one question need your help.

When I changed the clock output divider(CDCE72010) for TSW1400 and AFE722x card, the wave form I got will become abnormal.

The right setting for clock divider seem like:

/3 for AFE722x.
/4 for TSW1400.

What is the relationship of clock between AFE722x and TSW1400?
How can I have max sampling rate for AFE722x?

please kindly help it , Thanks.
