Hi Expert,

    Hi Elec,

    Thanks for your inquiry. There are a number of items which are important to consider when starting up the DS90UB633A. Consider the power up requirements detailed in section 8.1.2 of the 633A datasheet, this details the timing at which the various power supplies & PDB signal should be supplied to the 633A. Additionally, strapping the correct operating mode (external oscillator mode or PCLK mode) as seen datasheet section 7.4  is important to ensuring proper function of the device.

    If there’s any further guidance I can provide here please let me know!

    Best,

    Thomas

    Hi Thomas,

    How about register? Do I need software configuration before well working? Thanks.

    Hi Elec,

    I do not believe there is any need to manually set registers during startup of the DS90UB633A.
