Original question:

AFE7950EVM: Error: LOS Indicator for (Serdes Loss of signal) lane 0: 1

AFE7950EVM: I want to use the ADC and DAC at the same time

Part Number: AFE7950EVM
Other Parts Discussed in Thread: AFE7950

Tool/software:

After setting up the Latte, I configured the DAC with HSDC Pro and confirmed that the output was normal on the spectrum analyzer, then configured the ADC with HSDC Pro and confirmed that the ADC was working properly.
However, after configuring the ADC, the DAC output waveform became abnormal.
Is it possible to run the DAC and ADC at the same time?
I have set up the Latte with "S3_OnboardClk_RX_TX_500M_FB_disabled.py"

    Hi Yuuki,

    Can you share with TSW board you are using for your evaluation? If it is the TSW14J57 can you confirm if you are following 'Step 7: Change ini files' of the 'AFE7950+TSW14J57.pptx' bringup guide. After doing step 7 you will be able to use both the ADC and DAC at the same time.
