TSW14J56EVM: TIMED_OUT_ERROR connecting to ADC14x250EVM

Part Number: TSW14J56EVM

While following along  ADC14x250EVM user guide(SLAU625–November 2015)  i could not successfully capture data, obtained instead a TIMED_OUT_ERROR.  I observed D4 blinking and D3 OFF. I noticed that the GUI for the ADC14x250EVM has a button "Program LM04828" and that loads "Configuration 2" which appears to have certain values (Like "no SYSREF") that the TSW14J56 EVM  may not be expecting (?)  Perhaps the documentation is out of date? has anyone else had a problem with this? I'm new to JESD support and am using these platforms as my on ramp. Would appreciate any help, thanks!!

  • John,

    We will get back with you soon.

    Ken.
  • Thank Ken!

    Yeah, so i played around with the ADC14x250EVM-TWS14J56 combo a little more today and still not confident that the configuration supplied in the GUI for the LMK04828 is correct, so i'm still stuck.  It would be nice if there was a tool to generate an LMK04828 config file automatically, like from the clock design tool or something. That way i could rapidly change all dividers and VCO frequencies; right now i have to enter data into the clock design tool and manually copy the values over to the ADC14x250 GUI. I'm not 100 percent sure i am doing this correctly that way because some of the nomenclature for dividers is a little ambiguous between the GUI and the design tool.  Also, i'm not sure which clock outputs are being used for JESD ref clock. I believe it is CLKout8 and 9 but again, not sure...

  • Hi John,

    I tried the steps in the UG and get the same results you did. I think the clock output from LMK is not set correctly.

    I'm working on it and will update you.

  • Hi John,

    Do you see a change in current after programming the ADC?

    Can you also check the supply voltages going to the ADC? I checked few EVMs we have and they all seemed to be missing the ferrite beads (Z4, Z5, Z6...). So, just wanted to rule out an issue with the EVM.

    Regards,

    satish.

  • Yes, i see a current jump when programming and/or when i calibrate the board using the ADC14x250EVM GUI.

    I noted that all ferrites are installed and verified ADC supply voltages via TP3.0, TP1.8, TP 1.2 and TP1.2AUX. I believe teh EVM is working properly from an electrical perspective.

    Thank you

    John

  • I still need help with this

  • Ken- I still need help with this issue, we are dead in the water!
  • John,

    We have a new EVM in hand and will test it and get back to you if we find any issues.  Hopefully we will be able to get back with you fairly quickly.

    Ken

  • ok great, thanks Ken!

  • Hi John,

    I just went through the "Quick Start Guide" in the EVM User's Guide, and was able to get a capture in HSDC Pro using the ADC14X250 EVM Rev B and the TSW14J56 Rev D.

    After connecting/powering up all inputs to the boards as described in the Quick Start Guide, your setup should look like this.

    After connecting to HSDC Pro and loading the appropriate firmware and files (ADC14X250_LMF_112), your setup should look like this. Notice SYNC LED on ADC has gone out. Also, D3 (RX Sync) on the J56 has illuminated.

    Next, configure the ADC14X250 with the GUI by clicking both "Program LMK04828" then "Calibrate ADC14X250". There should not be any change to LEDs.

    Return to HSDC Pro and enter 250M in the "ADC Output Data Rate" field, and push enter. You should see a notification pop up like this.

    Now, click "Capture" and you should see D3 (RX SYNC) turn off and D4 (RX CLK) will start to blink. Also, notice that the SYNC LED on the ADC14X250 has illuminated. Most importantly, there will be a successful capture on HSDC Pro, as seen in the below pic.

    If you did not get the same results as I did after following my steps, please let me know at what point things were different for you, and we can start there.

    Also, please ensure that you have installed both the ADC14X250 GUI and the HSDC Pro Software as an administrator (right click on the respective setup file, "Run as Administrator").

    Regards,

    Dan

  • Dan- thanks for the detailed info. I wont be back in my lab until this Thursday. I will repeat all steps outlined in your email (which seem familiar, but i don't recall precise LED status ) and get back to you all with the results.
    John
  • Thanks again Dan!

    So the first thing i did was reinstall all SW, running installation as administrator.

    I connected the board and configured it with the ADC14x250 firmware from the high speed data converter pro SW(V4.70)  as instructed. Connection established and firmware appears to download. I observed DIFFERENT glowing LEDs on the TSW14J56 board than you did. (Specifically, only LEDS D3, 6 and 7 turn on) I did see the SYNC LED turn OFF on the ADC14x250 eval board. 

    Then i went ahead and programmed the LMK04828 on the ADC14x250EVM using .the GUI utility (ADC14x250EVM GUI)  The LEDs on the TSW14j56 board  ALL GO OUT. The SYNC Light on the ADC EVM turns back ON! 

    Continuing on with the steps above results in the WRITE _REGISTER_FAILED error, my originally reported problem. :( 

    Thanks

  • Hi there John,

    I'm sorry that you're still experiencing problems getting up and running! Do you happen to have another ADC/DAC EVM that can connect to your TSW14J56? The reason that I ask is that you mentioned that the LEDs (D6 and D7) on the J56  illuminate. According to slwu086c (TSW14J56 datasheet), if these stay illuminated, you may have an issue with your DDR memory.

    Let me talk with my team, and I'll get back to you soon.

    Regards,

    Dan

  • Dan-
    I did have another ADC EVM and when connected it to the TSM14J56 board and configured with ADC14x250 firmware (via the high speed data pro SW) it maintained the same LED pattern i reported yesterday (D6,7 and 3 illuminated). However when i then programmed the LMK04828 the LED did not go out as before. LEDs D3,6 and 7 of the TSW14J56 board stayed lit and the Sync LED on the ADC14xEVM stayed off.
    Thanks!
    John
  • John,

    Unfortunately, it seems as though your TSW14J56 board is the culprit. The LEDs D66 and D7 should not illuminate, and D8 should be lit. It appears that the DDR memory is having some kind of malfunction.

    I'm sorry that there isn't a direct solution that we can provide. I suggest returning the board through your supply/requisition channels, and trying again with a new J56.

    Before you return the board, could you please provide us the TSW14J56 device serial number? It is the identifier that comes up when you connect the board to HSDC Pro. This will help us determine the batch that this board came from. Thanks!

    Best,

    Dan
