I am currently using this chip to synchronize a sensor network ( more than 30 sensors ), the aim is to attend 1 ns precision. I am wondering about the switches added delays and the effects of cable length (about 100 m).
Any one worked or is working in a similar situation? Or anyone worked with this chip DP83640 (According to National Instrument the tinest attended precision is 3.85 ns)?
I would like to hear some feedbacks and some tips if possible in how to well make this device or IEEE 1588 work..
Many thanks
