Just as a data point, I used the DP83640 PHY in the past and got about
10ns, measured as the uncertainty in time-of-flight style physics
experiments. The PHY only supports 10/100M Ethernet, but is working with
LinuxPTP and can output synchronized clocks and triggers.
Best regards,

Hi Wolfgang, thanks! 10ns is excellent! I saw many references to DP83640
for PTP but we need to support Gb ethernet, I've found some Vitesse PHYs
(VSC8572, VSC8574, VSC8582, VSC8584) that should also work for 1Gb
ethernet, but I'm trying to find other alternatives, mainly because these
PHYs have
Hi Richard,
Thank you very much for your reply! We currently have a PTP implementation
done on an FPGA but we are looking for an alternative without using an FPGA
on simpler products. With the current implementation, we usually have an
accuracy better than 100ns (most of the time at around 60ns),

Hi all,
Is there a list of hardware that can be used with linuxptp to do
timestamping at the hardware level (on PHY or on MAC)? There are some phys
that support it, like the Vitesse / Microchip, etc., but is there a
compatibility list available?
I'm identifying components that can help the usage
