Speed

2.5G

1G/2.5G

1G/2.5G/10G

10M/100M/1G/2.5G/5G/10G

The operating speed of the PHY.
Enable IEEE 1588 Precision Time Protocol On, Off

Select this option for the PHY to provide latency information to the MAC. The MAC requires this information if it enables the IEEE 1588v2 feature.

This option is enabled only for 2.5G and 1G/2.5G.

Connect to MGBASE-T PHY On, Off

Select this option when the external PHY is MGBASE-T compatible.

This parameter is enabled for 2.5G, 1G/2.5G, and 1G/2.5G/10G (MGBASE-T) modes.

Connect to NBASE-T PHY On, Off

Select this option when the external PHY is NBASE-T compatible.

This parameter is enabled for 10M/100M/1G/2.5G/5G/10G (USXGMII) modes.

PHY ID (32 bit) 32-bit value

An optional 32-bit unique identifier:

  • Bits 3 to 24 of the Organizationally Unique Identifier (OUI) assigned by the IEEE
  • 6-bit model number
  • 4-bit revision number

If unused, do not change the default value, which is 0x00000000.
