AWR1243: Which signals are necessary in 120 pin connector in Devpack?

Part Number: AWR1243

Hi champion,
   My customer is debuging their own interface board like TI Devpack which is following TI design. Their board can work with Radar studio now, but can't work with TSW1400. They are checking the 120 pin connection on their board. In Devpack's schematics, there are many signals besides the LVDS/CSI2 signals. Could you double check whether all the signals in the schematics are needed?
   On customer's board, they connected pin 14,16, [20,22,26,28,32,34,38,40,44,46,50,52,56,58]->CSI2/LVDS, and 93, 94, 96, 106 to the desired signals. Are these signals enough to make TSW1400 work? Plus what is the usage of BP_LP_5V_IN in the connector?

Thanks,
Adam

    Hello Adam,
    If the radar studio is working fully then the only additional signals to be connected to the TSW1400 are only the LVDS lanes you have indicated above, nothing else is needed. The 5V_IN is not required for TSW1400, its meant for a host interface where the host can provide power supply also the radar device.

    Can you post the error you are getting and the steps you are following?

    Regards,

    Hello Adam,
    Did the capture work at the customer end?

    Hello Vivek,
    Thanks for your reply. You comments is correct, and the customer also verified that only LVDS lanes is used for TSW1400 data capture. The problem is still open and TSE1400 can't capture data with their own interface board. I suggested them to measure the LVDS signal quality, however they are working on some other high prority issure now and don't have time to debug on this issue. I think we can clost it timely and wait for their further progress.

    Thanks,
    Adam
