Hello,

Apologies for the delayed response.

The Triple-Speed Ethernet Intel FPGA IP supports the IEEE 1588v2 feature only in the following configurations:

• 10/100/1000-Mbps MAC with 1000BASE-X/SGMII PCS and embedded serial PMA without FIFO buffer in full-duplex mode

• 10/100/1000-Mbps MAC with 1000BASE-X/SGMII PCS and embedded LVDS I/O without FIFO buffer in full-duplex mode

• 10/100/1000-Mbps MAC without FIFO buffer in full-duplex mode

• 10/100/1000-Mbps Ethernet MAC with 1000BASE-X/SGMII 2XTBI PCS without FIFO buffer in full-duplex mode

So, SGMII is required for IEEE protocol.
