PGA900: OWI can't activate PGA900

Hello，PGA900 is one NDA product, did you have requested the full datasheet from the TI website?

thanks for your reply.I have already got the full datasheet.

OK, I need to confirm this question again, and I would reply you as soon as possible.

thanks a lot

No problem, and I would  reply to you once I  have confirmed about this problem. 

Hi Kailyn:

thanks for your reply.I  inputed  the OWI voltages directly at the VDD pin, But unfortunately , the IC PGA900 can't triggered the OWI activation interrupt. It seemed the IC was reset.

I don't know why.

Hi Kim,

Are you using your own board or the EVM board?  

Hi Kailyn:

    on my own board. 

thanks a lot , now I know the reason.  the slew rate on VDD should below 0.5V/us

    best regards.
