Yes, that is right. Disable the MAC's PHC driver or rip out its code.
Thanks,

It's not on the list (probably due to not being ptp-ready "out of the box"
under Linux) but Microsemi's VSC8572 (nee Vitesse) and family could do the
job (for 2-step PTP).

For various reasons we ended up not using this

It sounds like you are doing something very similar to what I
have not yet interfaced DP83640 since I would prefer to have a PHY with a 1Gb
interface if possible.

My goal is to get down to 10-20ns 1PPS jitter.
I am using a high stability external PTP clock reference for both master and
slave.

Hi
On my Cyclone V SoC board I have ptp running with HW timestamping in MAC
(stmmac), but I need even better accuracy, i.e. hardware timestamping in PHY.
Is my only option to use TI’s DP83640 PHY (which only supports 100Mb) or am I
