about ADC Buffer Source

Other Parts Discussed in Thread: AWR1843

I design a frame with 128 chirps to continue transmitting unless the power is turned off.
Probably, after AD conversion of this frame, it will be stored in DFE.

Should I choose DFE as the source for the ADC Buffer when sending this stored data to the ADC Buffer?
What happens if I select HIL as the input destination?

Hiroyuki-san,

What TI device are you using in this design. Seems it would be an AWR* or IWR* device, please verify.

Arrigato,

~Leonard

Hi LeonaldEllis.

I use AWR1843.

Hi,

Yes, you should select DFE.

If you select HIL as input, the input should not come from the RF Front End it should come from the DMM interface

Details of the DMM interface, which is used for HIL, can be found in the TRM document.

You can refer to the following thread for more details: https://e2e.ti.com/support/sensors/f/1023/t/861828

So, you would need to design some hardware that would provide the data through the DMM interface.

thank you
