[time-nuts] Re: Silicom PCIe timestamping network cards

[Bob kb8tq]

Hi

I think the key parameter is the 8 ns resolution on the time stamp. 
That may or may not be adequate for this or that application. 

Without doing a deep dive on the part, it’s not real clear how they
deal with the accuracy of the onboard timebase. It’s rated at 0.01 ppm
with no real details. Obviously if it is free running and there is no
practical calibration approach …. that will add to the error as well.
One would *hope* they thought about this ….you never know...

They have SMA in/out for a PPS signal in addition to the network interfaces. I've found datasheets like this (linked below), but no manuals or software. Has anyone used one of these in a lab before? I'm very tempted.
