10G Ethernet


So-Logic's solution to the 10 Gbit/s Ethernet consists from two cores:

  • 10 Gbit/s Ethernet MAC Controller Core, implementing Media Access Control sublayer,
  • 10GBase-R PCS Core, implementing 10GBase-R PCS/PMA sublayer.

Using only these two cores from So-Logic, user can easily and quickly build a complete 10 Gbit/s Ethernet solution.

10 Gbit/s MAC Controller core is used to encapsulate user payload into Ethernet frames. It implements MAC and MAC flow control layers as defined in the Std. 802.3-2008 specification. 10 Gbit/s MAC Controller core uses standard XGMII-SDR interface to connect to the lower level Ethernet PCS/PMA core, and AXI-Lite and AXI-Stream protocols to connect to the user logic.

10GBase-R PCS Core transforms the input TX XGMII frame to the physical TX signals and the physical RX signals to the RX XGMII frame. It implements the IEEE 802.3-2008 Ethernet specification, clause 49. This core can be used to connect to the majority of SFP+ 10G Ethernet Phy transceiver modules, allowing data communication over optical fiber medium.
