Hi,

I wanted to know does this phy chip take gps/gnss 1 pps signal for timestamping?

Hi Rishik,

Yes, PHY can timestamp rising edge of a signal. See section 7.3.1.3.2 of datasheet.

Thanks,

David

I can't find that section in the datasheet. Can you share the datasheet where it is mentioned and also where can I find the pin details of this chip. I am not seeing any details about the pin of this chip.

Thanks
