ADS8 : DERDES does not work

Hello,

I have a question about ADS8-V1EBZ.
I am verifying the operation of the ADS8-V1EBZ and AD9176-FMC-EBZ by request from our customer.
At first, the AD9716-FMC-EBZ worked but it stops working.
The Attached figure is the DPGLite GUI.
"PLL : cpll Not-locked" is indicated in the red rectangle area.
I confirmed using another ADS7-V2EBZ, it indicate "PLL : cpll Locked" and works well.



And then I tested using AD9208-3000EBZ too.
I can configure to AD9208 via ADS8 but I could not get sampled data. ( I confirmed the SERDES PLL locked, on ACE GUI)
The FPGA XCKU040-3FFVA1156E, which is on ADS8, looks to work with the exception that SERDES.

I need the cause of this trouble and solve it.
Could you teach me what problem is occurring on ADS8 and which circuit block should I check?

Best regards,

y_suzuki

    please provide screenshots. are you using the USB3.0 cable to connect the ADS8 to the AD9208-3000EBZ?

  • Hello,

    Thank you for your support.
    I send the screenshot.

    The above screenshot is in waiting for the waveform data but it was going on eternity.

    I am suspecting that the ADS8-V1EBZ may have H/W trouble.
    The LED status transit as follows.

    1. After power on, DS11, DS13, DS15, DS39, and DS16 are turned on Green.
    2. The FPGA fan start.
    3. After about 3.5sec from powered on, DS15 and DS39 are turned off and DS7 and DS10 are turned on Green. And DS17 flush a moment on Red.
    4. FPGA fan stop.

    5. Start the ACE
    6. Double click "AD9208-3000EBZ" on ACE GUI.
    7. DS16 and CR401(AD9208-3000EBZ) are turned on Green.
    8. DS15 is turned on and the FPGA fan start.
    9. DS1 and DS2 are turned on.

    10. Press the "Run Once" button and DS1 & DS2 are turned on Green.

    Is the transition of LED status true?
