DAC37J82: When JESD204B TX output is changed, the waveform of DAC output will never change

Part Number: DAC37J82

Hi team,

The customer configuration is shown below

At present, it can be determined that the clock from the LMK is correct. The CGS sequence and the data sent by the physical layer can be seen at the end of JESD204B TX. However, no matter how to modify the output waveform, the same waveform is always presented on the oscilloscope. It is unclear whether the data does not reach the DAC or there are other configuration errors in the middle.

Best Regards,

Amy Luo

  • Amy,

    Please send the DAC GUI Quick start tab screen shot. Are they using the TI DAC37J82EVM? What is used to send data to the DAC? If it is the TSW14J56EVM, send screen shots of the HSDC Pro GUI and LED status of both boards. Make sure both boards have 5V supplies that can provided 4A.

    Regards,
