    Hello,

    Because of the Thanksgiving holiday in the U.S., the E2E support responses will be delayed until the team is back on Monday, December 2.

    Thank you for your patience.

    Hi Nikitha,

    I took a look at your schematic, please see feedback below:

    1. AC capacitors - normally 0402 size capacitors are used rather than 0603, could you confirm if it's possible to use 0402?
    2. Do you have info available on the PoC network which was used here?
    3. No RC network included on PDB pin, please ensure that the power-up sequence is followed here.
    4. Latest mode table should be referenced, please see below:
    5. Please confirm what the desired mode is here, 10k pull up and 10k pull down don't appear to match this table.
    6. Same comment for IDX strap - please confirm what address should be used & select voltage divider resistors accordingly.

    Best,

    Thomas
