Select from the following standards for the core:
- 1000BASE-X
- 1000BASE-X Physical Coding Sublayer (PCS) functionality is designed to the IEEE 802.3 specification. Depending on the choice of physical interface, the functionality can be extended to include the 1000BASE-X Physical Medium Attachment (PMA) sublayer. Default setting.
- SGMII
- Provides the functionality to provide a GMII to SGMII bridge, as defined in the Serial-GMII Specification V1.7 (Cisco Systems, ENG-46158). SGMII can be used to replace GMII at a much lower pin count and for this reason is often favored by Printed Circuit Board (PCB) designers.
- BOTH
- (A combination of 1000BASE-X and SGMII). Combining the 1000BASE-X and SGMII standards lets you dynamically configure the core to switch between 1000BASE-X and SGMII standards. The core can be switched by writing through the MDIO management interface.
