ADS42JB69EVM plus JESD204B Translation Card plus TSW1405EVM

Other Parts Discussed in Thread: ADS42JB69EVM, ADS42JB69, TSW14J50EVM

Dear all,

I know the newest test solution for ADS42JB69EVM is using TSW14J56EVM, unfortunately I only have TSW1405EVM ADC Capture Board, but I found JESD204B Translation Card in our laboratory.


I want to use ADS42JB69EVM,JESD204B Translation Card and TSW1405EVM for my data acquisition system design, because I checked the firmware file of TSW1405EVM and found ADS42JB69 is compatible through "16B_SAMPLE_WISE_EDGE".

I was confused by the interface between JESD204B Translation Card and TSW1405EVM when doing custom design. I need to know which 16 pairs on TSW1405EVM is used by "16B_SAMPLE_WISE_EDGE" firmware.

Because JESD204B Transiation Card is no long available, so I couldn't download the schematic of JESD204B Translation Card form TI website, I also checked Lattice website and found nothing about "16B_SAMPLE_WISE_EDGE" firmware.

Is there anybody can give me the shematic of JESD204B Transiation Card? Thanks.

  • Minglei,

    TI does offer a lower cost solution board, called the TSW14J50EVM, that works with the ADS42JB69EVM. Unfortunately, the JESD204B Translation Card is no longer supported. If you still want to attempt what you are doing, I have attached the schematics to the Translator Card, Rev C. I will look into trying to find out which 16 pairs are used by the TSW1405 in 16B_SAMPLE_WISE_EDGE mode.

    Regards,

    Jim

  • Hi Jim,

    Thank you for the schematic that you send to me.

    I checked TSW1400 ADC Interface in the second page of JESD204B Translation Card's schematic, and then compared it with Samtec interface of TSW1405EVM and TSW1400EVM to try to find out the relation between them. I still couldn't get the real connection maps between JESD204B Translation Card and TSW1405EVM.

    Yes, please help me to find out which 16 paird are used by the TSW1405 in 16B_SAMPLE_WISE_EDGE mode.

  • Minglei,

    Using this info below which is the pinout info from a compiled design for the translator board when using the ADS42JB69 and the TSW1400, you should be able to figure which pins to use. The last column shows the connector pin numbers used for the p/n LVDS ADC output pairs.

    Regards,

    Jim

  • Thanks, Jim. Through the pinout info above, I can get what I want.
