    Hi, regarding the sch. review, pls check TI's EVM board design user guide in www.ti.com, you can follow up or copy TI's design. some points:
    1. checking the pinout definition is correct or not?
    2. checking the power supplies filter design , the ripple or total noise is limited to 25mV (recommendation), and power supply sequence.
    3. mode_sel is correct or not based on d/s definition and your system design request.

    regards,
    Steven
