Hi,

Sorry for the confusion on AN849. This reference design is not meant to showcase 1588 functionality but rather focus more to showcase the low latency achievement.

For the LL 10G MAC - yes, PTP 1599 options will be disabled once 10GBASE-R register mode is turned on.

For 10GBASE-R 1588 reference design, I would recommend you to generate it using LL 10G MAC IP + Multirate PHY IP. Attached is the screenshot of selecting the preset in LL 10G MAC IP.

The 10G protocol support in Multirate PHY IP is actually 10GBASE-R as show in another screenshot below.

Thanks.
