Hi kang

Thanks for your support.

I checked the app notes but couldn't find a way to test the repeater mode.

Only testing requirements and test results are indicated in the app note.

I need detail data on how to test of repeater mode.

best regards.

Hi Louis,

please find attached for more details:

AFE76xx Repeater Loop Back Mode - No JESD204B Required.zip

Hi Kang

I also have the data you sent.

Could you please explain in detail what to do with the cfg file?

Could you test repeater mode with the AFE7686EVM?

Best regards.

Louis,

You will need to first configure the ADC/DAC with the same JESD204 mode and the same LMFS, same data rate. Once configured, you may use the loopback script to enable JESDTX to talk to internal JESDRX. It is described in the application note.
