5.5. 1GbE Parameters

The 1GbE parameters allow you to specify options for the 1GbE mode.
Table 50.  1Gb Ethernet Parameters
Parameter Name Options Description
Enable 1Gb Ethernet protocol On/Off When you turn this option On, the core includes the GMII interface and related logic.
Expose MII interface On/Off When you turn this option On, the core exposes the MII interface and related logic.
Enable IEEE 1588 Precision Time Protocol On/Off When you turn this option On, the core includes a module in the PCS to implement the IEEE 1588 Precision Time Protocol.
PHY ID (32 bit) 32-bit value

An optional 32-bit value that serves as a unique identifier for a particular type of PCS. The identifier includes the following components:

  • Bits 3-24 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.

PHY Core version (16 bits) 16-bit value This is an optional 16‑bit value identifies the PHY core version.
Reference clock frequency 125.00 MHz

62.50 MHz

Specifies the clock frequency for the 1GBASE‑KR PHY IP Core. The default is 125 MHz.
