  • TI Thinks Resolved

TX-SDK-V2/NOPB

Ultrasound beamformer TX-SDK-V2/NOPB is not working.

3.3 V supply voltage and ground are shorten together.

  • Hello Dong,

    I am searching for the applications engineer who owns these devices at TI.

    Hello Dong,

    I notified the team, who supports this evaluation module.

    As a note, this evaluation module has been removed from the web, and it may no longer be supported.

    Hello Mintack,

    I believe that this EVM is obsoleted, so support for it is limited. I've contacted the applications engineer again.

    Thanks. Because almost same situation on my board too. some voltages are short with GND now.

    I knew that lm96551 is after version of lm96550.

    So can I replace the lm96550 to lm96551 in SDK-TX-V2/NOPB??

    Because lm96550 is discontinued product. thank you.

    <Not short>
    : 1.8v, -50v, +50v, 40v, -40v

    <short with GND>
    -5v +5v 3.3v SUB -10v +10v
  • In reply to Mintack Oh:

    Hello Mintack,

    Technically, the TX-SDK-V2 can be used for the LM96551 too as long as one doesn't apply any voltages to VPF and VNF pins.
    For the LM96551, the floating supplies are generated internally.

    Mintack,

    It seems like the device is damaged.
    The power supply sequencing in the User Guide should be followed strictly to avoid damaging the part.

    Regards
