    HI Kevin,

    The PDB cap should be 10uF.

    Is there a reason why the customer is using AON mode rather than sync mode? If they are using sync mode, they can simply use the 4G PoC network in the datasheet. But if they are using AON mode, the back channel is lower and they'll need to make sure the PoC network can block the back channel.

    Best,
